A river has an average rate of water flow of 59.6 M3/s. This river has three tributaries, tributary A, B and C, which account for 36%, 47% and 17% of water flow respectively. How much water is discharged in 30 minutes from tributary B?
Answers
Answer:
50421.6 m³
Explanation:
The river has an average rate of water flow of 59.6 m³/s.
Tributary B accounts for 47% of the rate of water flow. Therefore the rate of water flow through tributary B is:
Flow rate of water through tributary B = 47% of 59.6 m³/s = 0.47 * 59.6 m³/s = 28.012 m³/s
The volume of water that has been discharged through tributary B = Flow rate of water through tributary B * time taken
time = 30 minutes = 30 minutes * 60 seconds / minute = 1800 seconds
The volume of water that has been discharged through tributary B in 30 seconds = 28.012 m³/s * 1800 seconds = 50421.6 m³
Explain why the scenario below fails to illustrate an understanding of the importance of metrology. Situation: Natalie is a calibration technician at a food production plant. Natalie: "The oven is just a couple of degrees off. I will just wait a few hours to see if it will level out on its own"
Answers
Answer:
Explanation:
The situation being described completely fails in regard to the importance of metrology. This is because the main importance of metrology is making sure that all of the measurements in a process are as accurate as possible. This accuracy allows an entire process to function efficiently and without errors. In a food production plant, each individual department of the plant relies on the previous function to have completed their job with the correct and accurate instructions so that they can fulfill their functions correctly and end up with a perfect product. If the oven (like in this scenario) is a couple of degrees off it can cause the product to come out burned or undercooked, which will then get transferred to the next part of production which will also fail due to the failed input (burned or undercooked product). This will ultimately lead to an unusable product at the end of the process and money wasted. Which in a large production plant means thousands of products in a single batch are thrown away.
In terms of the necessity of metrology, the situation stated absolutely fails. This is because metrology's primary goal is to ensure that all measurements in a process are as precise as feasible. This precision allows a whole process to run smoothly and error-free. If the oven temperature is wrong by a few degrees, the product will come out charred or undercooked, and the product will be sent to the next step of the process, which will also fail owing to the failed input. This will result in a useless product and a waste of money at the end of the procedure. In a big manufacturing facility, this means thousands of goods are discarded in a single batch.
A spherical tank with a radius of 0.25 m is filled with water (ρ = 1000 kg/m3). Calculate the mass and weight of the water in SI units.
Answers
The mass of the water is 65.5 kg. The weight of the water is 641.9 kgm/s²
What is the mass of a spherical tank?The mass of a spherical tank is the space contained in the tank. The mass of the spherical tank can be determined by first finding the volume of the tank, then using the relation of density, mass, and volume to find the mass.
From the given parameter:
The radius of the tank = 0.25 mThe density of the water = 1000 kg/m³The volume of the tank can be determined by using the formula:
\(\mathbf{V = \dfrac{4}{3}\pi r^3}\)
\(\mathbf{V = \dfrac{4}{3}\pi (0.25)^3}\)
V = 0.0655 m³
Using the relation that:
\(\mathbf{Density = \dfrac{mass}{volume}}\)
\(\mathbf{1000 \ kg/m^3= \dfrac{mass}{0.0655 \ m^3}}\)
mass = 1000 kg/m³ × 0.0655 m³
mass = 65.5 kg
The weight of the water can be determined by using the formula:
Weight = mass × gravity (i.e. acceleration due to gravity)
Weight = 65.5 kg × 9.8 m/s²
Weight = 641.9 kgm/s²

The mass of the water in spherical tank is 65.4kg.
The weight of the water in spherical tank is 640.8 Newtons.
Given the data in the question:
Radius of the spherical tank; \(r = 0.25m\)Density of water; \(p = 1000kg/m^3\)Mass of water; \(m_w = \ ?\)
Weight of water; \(Ww = \ ?\)
DensityDensity \(p\) is simply the measure of the compactness of the mass of a substance. It is expressed as;
\(Density = \frac{Mass}{Volume}\)
To determine the mass and weight of the water in spherical tank,
we calculate the Volume of the spherical tank.
\(V = \frac{4}{3}\pi r^3\)
We substitute in our given values
\(V = \frac{4}{3} * \pi * (0.25m)^3\\ \\V = \frac{4}{3} * \pi * 0.015625m^3\\\\V = 0.0654 m^3\)
Now, we calculate the mass of the water; using the expression above.
\(Density = \frac{Mass}{Volume}\\Mass = Density * Volume\\\)
We substitute in our values
\(Mass = 1000kg/m^3 \ *\ 0.0654m^3\\\\Mass = 65.4kg\)
Hence, the mass of the water in spherical tank is 65.4kg.
Next we calculate the Weight which is expressed as;
\(Weight = mass\ *\ Acceleration\ of\ gravity\)
Where acceleration of gravity \(g = 9.8m/s^2\)
We substitute in our values
\(Weight = 65.4kg * 9.8m/s^2\\\\Weight = 640.8kgm/s^2\\\\Weight = 640.8N\)
Therefore, the weight of the water in spherical tank is 640.8 Newtons.

In a water jet macning, the mass flow rate of water is found to be 0.05 kg/s. consider water density as 996 kg/m and 0.02 cm is the diameter of the hole from which water jet comes out. neglect all the losses and potential head differences. determine the minimum pressure at which water suppling pump must operate.
Answers
The minimum pressure at which the water-supplying pump must operate is approximately 2.45 x 10⁶ Pa or 2450 bar.
Solution:To calculate the minimum pressure at which the water-supplying pump must operate, we need to use the formula for the volumetric flow rate of a fluid:
Q = A * v
where,
Q =the flow rate
A = the cross-sectional area of the hole
v = the velocity of the fluid.
We can use this formula to determine the velocity of the water, and then use the Bernoulli equation to determine the minimum pressure.
From the question:
ṁ=0.05 kg/s
ρ= 996 kg/m
d= 0.02 cm
Calculating the area of the hole:
A = (π/4) * (d²)
where,
d is the diameter of the hole, and pi is approximately 3.14.
d = 0.02 cm = 0.0002 m
A = (3.14/4) * (0.0002 m)² = 1.57 x 10⁻⁷ m²
Using the mass flow rate to calculate the velocity of water:
Q = ṁ / ρ
where,
Q = the volumetric flow rate
ṁ = the mass flow rate
ρ = the density of water.
Q = (0.05 kg/s) / (996 kg/m³)
Q = 5 x 10⁻⁵ m³/s
Using the area of the hole to find the velocity of water
v = Q / A
v = (5 x 10⁻⁵ m³/s) / (1.57 x 10⁻⁷m²)
v = 318.8 m/s
Using the Bernoulli equation to find the pressure:
P = Patm + (1/2) * ρ * v²
where,
P = the pressure
Patm = the atmospheric pressure
ρ =the density of water
v = the velocity of the water.
P = Patm + (1/2) * (996 kg/m³) * (318.8 m/s)²
Hence, the minimum pressure at which the water-supplying pump must operate is approximately 2.45 x 10⁶ Pa or 2450 bar.

The blade divides the water evenly at an angle of θ-45° Express your answer to three significant figures and include the appropriate units. Figure 1 of 1 F-Value Units 40 mm Submit Request Answer Provide Feedback Next
Answers
From the given information, we can calculate the flow rate of water through the nozzle as follows:
Q = A * V
where Q is the flow rate, A is the cross-sectional area of the nozzle, and V is the velocity of the water.
The cross-sectional area of the nozzle can be calculated as:
A = (π/4) * d^2
where d is the diameter of the nozzle.
Substituting the given values, we get:
A = (π/4) * (0.04 m)^2 = 0.0012566 m^2
The flow rate can now be calculated as:
Q = A * V = 0.0012566 m^2 * 20 m/s = 0.02513 m^3/s
The force exerted by the water on the blade can be calculated using the momentum equation:
F = ρ * Q * V * tan(θ-45°)
where ρ is the density of water, and θ is the angle at which the water hits the blade.
Assuming a density of water to be 1000 kg/m^3, we get:
F = 1000 kg/m^3 * 0.02513 m^3/s * 20 m/s * tan(θ-45°)
Substituting θ = 45° (since the water is hitting the blade at an angle of θ-45°), we get:
F = 1000 kg/m^3 * 0.02513 m^3/s * 20 m/s * tan(0°) = 0 N
Therefore, the horizontal force exerted by the water on the blade is 0 N. This is because the water hits the blade at a perpendicular angle and there is no component of force in the horizontal direction.

When engine power is increased, the constant-speed propeller tries to function so that it will?
Answers
When engine power is increased, the constant-speed propeller tries to function so that it will maintain a constant rotational speed.
The constant-speed propeller is designed to automatically adjust its pitch in response to changes in engine power. This allows it to maintain a consistent rotational speed, even as the engine power increases. As the engine power increases, the propeller blades will adjust their pitch to a finer angle, which creates more lift and allows the propeller to maintain a constant rotational speed. This is important because it ensures that the propeller operates efficiently and optimally, allowing the aircraft to achieve maximum performance. Without this automatic adjustment, the propeller would struggle to maintain a consistent speed, resulting in inefficient operation and potential damage to the engine and propeller.

Counting the time to examine or modify a bit as THETA(1), show how to implement a counter as an array of bits so that any sequence of n INCREMENT and RESET operations takes time O(n) on an initially zero counter. (Hint: Keep a pointer to the high-order 1.)
Answers
Including a DECREMENT operation in the k-bit counter example would result in a worst-case time complexity of Θ(nk) for n operations.
This is because each DECREMENT operation would require iterating through all k bits to determine the bit to decrement, resulting in a linear time complexity for each DECREMENT operation. Thus, for n DECREMENT operations, the overall time complexity would be Θ(nk).In a k-bit counter, each bit represents a power of 2. When performing a DECREMENT operation, we need to identify the rightmost set bit and decrement it. This requires scanning all k bits until the rightmost set bit is found. As the number of bits (k) increases, the time required for each DECREMENT operation grows linearly. Therefore, for n DECREMENT operations, the time complexity would be Θ(nk).

Knowing that rods AB and BD are of diameters 1. 25 in. And 1. 75 in. , respectively, determine the maximum shearing stress in each rod. Neglect the effect of fillets and of stress concentrations. It is given that P= 135 lb. The maximum shearing stress in rod AB is __________ psi. The maximum shearing stress in rod BD is __________ psi
Answers
Stress is defined as the internal resistance offered by a body to an external load. The force per unit area is the unit of stress. If a force P is applied at a distance l from the end of a bar of cross-sectional area A, the stress is given by the formula:
\(Stress = P / A\)where P is the applied load, A is the cross-sectional area of the material on which the load is applied. Rods AB and BD have diameters of 1.25 in. and 1.75 in., respectively. We can calculate their cross-sectional areas using the following formula : \(Area = π r²\)where r is the radius of the rod.
AB has a diameter of 1.25 in. Thus, its radius is 1.25/2 = 0.625 in. The cross-sectional area of AB is:
\(π (0.625)² = 0.616\)in²BD has a diameter of 1.75 in. Thus, its radius is 1.75/2 = 0.875 in.
The cross-sectional area of BD is :\(π (0.875)² = 2.405 in²\)
Now we can calculate the maximum shearing stress in each rod using the following formula:
\(τ = P / A\) where P is the applied load and A is the cross-sectional area of the rod.
A load of 135 lb is applied to the rods. Thus, the maximum shearing stress in AB is:
\(τ = 135 / 0.616 = 219.16 psi\) (rounded to two decimal places)
The maximum shearing stress in BD is:\(τ = 135 / 2.405 = 56.03 psi\)(rounded to two decimal places)
the maximum shearing stress in rod AB is 219.16 psi, and the maximum shearing stress in rod BD is 56.03 psi.

Name three factors that cause the magnetic field to rotate. Select one or more: A. THE ARRANGEMENT OF THE STATOR WINDINGS B. NUMBER OF STATOR POLES PER PHASE C. THE VOLTAGES REVERSE POLARITY AT REGULAR INTERVALS D. FREQUENCY OF THE APPLIED VOLTAGE E. THE NUMBER OF TURNS OF WIRE IN THE ROTOR
Answers
Three factors that cause the magnetic field to rotate in an electric motor are : the arrangement of the stator windings, the number of stator poles per phase, and the voltages reversing polarity at regular intervals.
So, the correct answer is A, B and C
The stator windings are strategically arranged to create a rotating magnetic field when an alternating current (AC) is applied. The number of stator poles per phase affects the speed and torque of the motor, with more poles leading to a slower rotation.
Lastly, the voltages reversing polarity at regular intervals, due to the AC supply, generate a continuous rotation of the magnetic field, driving the rotor to follow this rotation.
Hence, the answer of the question is A, B and C.

if the velocity of money is 3, the money supply in this economy is
Answers
The velocity of money refers to the speed at which money is exchanged for goods and services within an economy. In other words, it measures how frequently money changes hands.
If the velocity of money is 3, this means that each unit of currency is used to buy goods and services three times within a given period, such as a year. This indicates a relatively active economy with a high level of economic activity. The formula for calculating the money supply in an economy is given by: Money Supply = Velocity of Money x Nominal Gross Domestic Product (GDP).
Therefore, if the velocity of money is 3 and the nominal GDP of the economy is known, we can calculate the money supply. This formula shows that the level of money supply is dependent on both the velocity of money and the level of economic activity within an economy.

The velocity of money refers to the rate at which money is changing hands in the economy.
If the velocity of money is 3, it means that each dollar of the money supply is being spent 3 times per year or, in other words, the money supply is being turned over 3 times per year. Therefore, we can calculate the money supply in this economy by dividing the total nominal GDP by the velocity of money. This can be represented by the following formula:MV = PYWhere:M = money supplyV = velocity of moneyP = price levelY = real outputLet's assume that the nominal GDP of this economy is $300 billion. If the velocity of money is 3, then the money supply in this economy can be calculated as follows:M = PY/V = $300 billion / 3 = $100 billionTherefore, the money supply in this economy is $100 billion.

technician a says that the front wheel bearings on a typical fwd car are pressed in and out of the steering knuckle assembly. technician b says that the front wheel bearings on a typical fwd may be bolted into the steering knuckle. who is correct?
Answers
Both A and B are correct. Front-wheel drive cars frequently have press-fit cartridge-style wheel bearings installed in the knuckles.
On many cars, both the front and the rear wheel bearings are typically sealed inside bolt-on hub assemblies. Uneven weight distribution over the contact patch may result from underinflated tires starting to lose their correct form. Both tread edges may begin to deteriorate noticeably more quickly than other parts of the tire if they are subjected to increased weight. The wheelset's dynamic unbalance will increase, increasing the lateral force, derailment coefficient, and wheel unloading ratio as well as decreasing the hunting critical speed and the quality of the vertical ride. Dynamic imbalance can also be brought on by a damaged tire or wheel, however it typically results from manufacturing variances. Dynamic imbalance, of course, degrades ride quality and tends to hasten the deterioration of tire and steering and suspension system parts.
