A water jet leaves a fixed nozzle with a velocity of 10 m/s. The jet diameter is 10 cm. A 30° cone is pushed into the water jet at a speed of 5 m/s. The water impinges on the cone with the jet axis and the cone axis in perfect alignment so that the water is divided evenly by the cone. Bernoulliâs equation suggests that because the pressure on the jet boundary is constant, the water velocity relative to the cone surface is constant.

Required:
Determine the thickness of water stream when it reaches the base of the cone.

Note as far as material science is concerned, that to create a ceramic matrix reinforcement material, I would use a ceramic material with high strength and stiffness such as silicon carbide.

This is because it has a high melting point.

I would next use chemical vapor deposition or melt spinning to convert the ceramic material into a fibrous shape, resulting in a fibrous ceramic matrix composite.

Because of the intrinsic qualities of the ceramic matrix, the resultant composite would have high stiffness and tensile strength, making it perfect for applications requiring great strength and endurance, such as aerospace or automotive components.

Answer:

1) 4.41 * 10^-4 kw

2) 2.20 * 10^-4 kw

Explanation:

Given data:

Filter = 500 m^3/min

dust velocity = 3g/m^3

bag ; length = 3 m , diameter = 0.13 m

change in pressure = 1 kPa

efficiency = 60%

1) Calculate the Fan power

First :

Calculate the total dust loading = 3 * 500 = 1500 g

To determine the Fan power we will apply the relation

\(n_{o} = \frac{\frac{p}{eg*Q*h} }{1000}\)    = \(\frac{\frac{p}{(3*10^{-3})* 981*( 500/60) *3 } }{1000}\)

fan power ( \(n_{0}\) ) = 4.41 * 10^-4 kw

2) calculate power drawn

change in P = 6 atm = 6 * 10^5 pa

efficiency compressor = 50%

hence power drawn = 4.41 * 10^-4 kw  * 50% = 2.20 * 10^-4 kw

The center of gravity, also known as the balance point or point of rotation when an object is permitted to freely rotate, is the average location of an object's weight.

All objects with mass are attracted to one another by the gravitational attraction, which has a magnitude that is directly proportional to the masses of the two objects and inversely proportional to the square of their distance from one another.

By means of gravity, a planet or other body pulls items toward its core. All the planets are maintained in their orbits around the sun by the force of gravity.

Any particle of matter in the universe will gravitate toward any other with a force that varies directly as the product of the masses and inversely as the square of the distance between them, according to Newton's law of gravity.

The given problem involves a 200 kg object sliding down a 10-meter-long ramp inclined at an angle of 40 degrees from the horizontal. As air resistance and friction are negligible, we can use the conservation of mechanical energy to solve for the object's velocity at the bottom of the ramp.

Initially, the object has only potential energy due to its height, which can be calculated as h = 10 * sin(40°). The potential energy (PE) is given by the formula PE = mgh, where m = 200 kg, g = 9.81 m/s², and h is the height.
When the object reaches the bottom of the ramp, all its potential energy is converted into kinetic energy (KE), which is given by the formula KE = (1/2)mv², where m = 200 kg and v is the final velocity in m/s.
Using conservation of mechanical energy, we equate the potential energy and kinetic energy: mgh = (1/2)mv². We can cancel the mass (m) from both sides of the equation and solve for the final velocity (v).
After calculating the height and solving the equation for v, you will find the object's velocity at the bottom of the ramp in m/s. Remember to maintain accuracy and professionalism when presenting your final answer.

When a dielectric is inserted into a capacitor connected to a battery, the energy stored in the capacitor increases. This is because the electric field between the plates decreases due to the presence of the dielectric, which leads to an increase in capacitance and an increase in energy stored in the capacitor.

The capacitance is defined as the ability of a capacitor to store energy in the form of an electric charge, and it is directly proportional to the distance between the plates and inversely proportional to the dielectric constant of the medium between the plates.

The work done in the process of inserting a dielectric into a capacitor is given by the equation W = Fd, where W is the work done, F is the force required to insert the dielectric, and d is the distance over which the force is applied. The force required to insert the dielectric is proportional to the change in electric field between the plates, which in turn is proportional to the dielectric constant of the medium.

The energy stored in a capacitor connected to a battery increases when a dielectric is inserted, and the work done in the process depends on the dielectric constant of the medium.

Explanation:

This is the operand for division in python and some other languages.

The system's temperature is maintained constant using an isothermal process, which is a type of thermodynamic process. Thermal equilibrium is maintained because heat is introduced or removed from the system so gradually.

Any isothermal process must have zero change in internal energy since the change in internal energy depends on the change in temperature, which is zero for all isothermal processes.

Since the temperature is kept constant, the energy change is zero (U=0). Thus, the work that the ideal gas does on its surroundings is equal to the heat that the gas absorbs.

Therefore, In a closed system, refrigerant-134a undergoes an isothermal procedure at 320 kPa and 40 °C until its quality reaches 45%. Determine the effort and heat transfer needed on a per-unit-mass basis. 2: 40.6 kJ/kg and 130 kJ/kg.

Answer:

To calculate the convolution of x(t) and h(t), we need to use the following formula:

y(t) = integral from 0 to t of {x(tau) h(t - tau) d(tau)}

First, we need to find x(tau) and h(t - tau):

x(tau) = u(tau - 3) - u(tau - 5)

h(t - tau) = e^(-3(t - tau)) u(t - tau)

Substituting these into the convolution formula, we get:

y(t) = integral from 0 to t of {(u(tau - 3) - u(tau - 5)) e^[-3(t - tau)] u(t - tau) d(tau)}

Since u(tau - 3) and u(tau - 5) are step functions, they are non-zero only when tau >= 3 and tau >= 5, respectively. Therefore, the integral can be broken up into two parts:

y(t) = integral from 3 to t of {(u(tau - 3) - u(tau - 5)) e^[-3(t - tau)] d(tau)}

- integral from 5 to t of {(u(tau - 5)) e^[-3(t - tau)] d(tau)}

Simplifying this, we get:

y(t) = (e^(-3t)) [integral from 3 to t of e^(3tau) d(tau) - integral from 5 to t of e^(3tau) d(tau)]

- e^(-15t) integral from 5 to t of e^(3tau) d(tau)

Evaluating the integrals, we get:

y(t) = (1/3) e^(-3t) [e^(3t) - e^(9)] u(t - 3) - (1/3) e^(-3t) [e^(3t) - e^(15)] u(t - 5)

Therefore, the convolution of x(t) and h(t) is:

y(t) = (1/3) e^(-3t) [e^(3t) - e^(9)] u(t - 3) - (1/3) e^(-3t) [e^(3t) - e^(15)] u(t - 5)
