At time t=2 min, the concentration inside the tank is 0.042 kg/kg and the concentration outside the tank is 0.476 kg/kg.

To determine the concentration inside and outside the tank at 2 minutes, we need to use the mass balance equation:

mass in - mass out + mass generated = change in mass in the tank

At time t=0, the mass in the tank is 8 kg, and there is no mass generated. Thus, we have:

(2.2 + 0.2) kg/min - 2 kg/min + 0 kg/min = dM/dt

Simplifying, we get:

dM/dt = 0.4 kg/min

Integrating both sides, we get:

M(t) = M(0) + (dM/dt) * t

Plugging in the values, we get:

M(2) = 8 kg + (0.4 kg/min) * 2 min = 9.6 kg

Now, we can calculate the concentration inside and outside the tank:

Concentration inside the tank:

At time t=0, the concentration inside the tank is:

Cin(0) = 0 kg/kg (since there is no salt in the tank initially)

At time t=2 min, the amount of salt in the tank is:

Min(2) = 0.2 kg/min * 2 min = 0.4 kg

Thus, the concentration inside the tank is:

Cin(2) = Min(2) / M(2) = 0.4 kg / 9.6 kg = 0.042 kg/kg

Concentration outside the tank:

The rate of salt leaving the tank is 2 kg/min, and at time t=2 min, the total amount of salt leaving the tank is:

Mout(2) = 2 kg/min * 2 min = 4 kg

Thus, the amount of salt remaining in the tank is:

Mrem(2) = M(0) + Min(2) - Mout(2) = 8 kg + 0.4 kg - 4 kg = 4.4 kg

The total mass leaving the tank is 2 kg/min * 2 min = 4 kg. Thus, the concentration outside the tank is:

Cout(2) = Mout(2) / (M(0) + Min(2)) = 4 kg / 8.4 kg = 0.476 kg/kg

Therefore, at time t=2 min, the concentration inside the tank is 0.042 kg/kg and the concentration outside the tank is 0.476 kg/kg.

Whenever 1000 elements and 1111 nodes are created, the Fluent will have a total of 20 values.

An algebraic equation, also known as a polynomial equation, is a mathematical equation of the form P=0, where P is a polynomial with coefficients in some field, most commonly the field of rational numbers.

The number of elements along the x direction is m, and the number of elements along the y direction is n.

So,

m × n = 1000 ( Elements)

m × n + m + n + 1 = 1111 (Nodes)

m + n = 1000

If m = 100 then n = 10. These values satisfy both the equations.

Each element will now have one velocity, pressure, or temperature component. So, for each case, there will be 1000 algebraic simultaneous equations.

Answer:

Scientists were surprised to find that Ötzi the Iceman's stomach contained remnants of red deer meat, as it had been previously assumed that his diet consisted primarily of plants. This finding provided new insights into the dietary habits of Copper Age Europeans and challenged previous assumptions about their reliance on agriculture. Additionally, the presence of the red deer meat in Ötzi's stomach suggested that he had eaten a last meal that was high in fat and protein, which may have provided him with the energy needed for his fateful journey through the Alps.

Answer:

Ötzi the Iceman was a well-preserved mummy found in the Italian Alps in 1991. One of the most interesting things about his remains was the discovery of his last meal. Analysis of his stomach contents showed that he had recently eaten a meal of ibex meat, a type of wild goat that lived in the region, and a type of ancient bread made from einkorn wheat. What surprised scientists was the presence of the ibex's stomach contents in Ötzi's stomach. They discovered that Ötzi had eaten the ibex meat raw, with no signs of cooking. This was surprising because it was previously believed that prehistoric humans only ate meat that had been cooked over fire. The discovery of the raw meat in Ötzi's stomach suggested that prehistoric humans may have eaten raw meat more often than previously thought and that cooking food may not have been as prevalent in ancient societies as previously believed.

Answer: the shear strength at a depth of 12 ft is 1034.9015 lb/ft²

Explanation:

Given that;

Weight of soil r = 118 lb/ft³

stress parameter C = 250 lb/ft²

φ total = 29°

depth Z = 12 ft

The shear strength on a horizontal plane at a depth of 12ft

ζ = C + δtanφ

where δ = normal stress

normal stress δ = r × z = 118 × 12 = 1416

so

ζ = C + δtanφ

ζ = 250 + 1416(tan29°)

ζ = 250 + 1416(tan29°)

ζ = 250 + 784.9016

ζ = 1034.9015 lb/ft²

Therefore the shear strength at a depth of 12 ft is 1034.9015 lb/ft²

Answer:

The outer diameter of the ball is 6.2138 cm

Explanation:

The formula to apply is ;

Heat loss ,

\(Q/t=kA*\frac{( T_1-T_2)}{d}\)

where ;

Q/t=total heat loss from the ball = 1600 w

k=coefficient of heat transmission through the ball= 2.75 W/m.˚C

A=area in m² of the ball with the coefficient of heat transmission

T₁=Hot temperature

T₂=Cold temperatures

d=thickness of the ball

Area of spherical ball using internal diameter, 3cm= 0.03 m will be

Radius = half the diameter = 0.03/2 = 0.015

Area = 4 *π*r²

Area = 4*π*0.015² = 0.002827 m²

Apply the formula for heat loss to get the thickness as:

1600 = {2.75 * 0.002827 *(250-30 ) }/d

1600 =1.711/d

1600d = 1.711

d=1.711/1600 = 0.001069 m

d= 0.1069

Using internal radius and the thickness to get outer radius as;

3 + 0.1069 = 3.1069 cm

Outer diameter will be twice the outer radius

2*3.1069 = 6.2138 cm

The network cable type that is virtually immune to signal interference is d. fiber-optic.

Fiber-optic cables use light signals to transmit data, making them highly resistant to signal interference. Unlike other cable types that use electrical signals, fiber-optic cables transmit data through optical fibers, which are made of glass or plastic. The data is converted into light pulses and transmitted through the fiber-optic cables using total internal reflection.

Fiber-optic cables offer several advantages over other cable types. Firstly, they are not affected by electromagnetic interference (EMI) or radio frequency interference (RFI) since they do not carry electrical signals. This immunity to interference ensures reliable and high-quality data transmission. Additionally, fiber-optic cables have a greater bandwidth capacity and longer transmission distances compared to other cable types.

In contrast, other cable types like STP (Shielded Twisted Pair), UTP (Unshielded Twisted Pair), and coaxial cables are more susceptible to signal interference due to their reliance on electrical signals for data transmission.

STP and coaxial cables provide some level of shielding against interference but are not as immune as fiber-optic cables. UTP cables, on the other hand, have no additional shielding and are more prone to interference.

Answer:

a) surface temperature is 70.196 °F

b) temperature at a depth of 2.5 ft, after 55 min is 58.426 °F

Explanation:

We know that the surface of semi-infinite copper slab is given as;

T - Ti = (2q₀√(∝t/π))/KA exp( -x²/4∝t) -q₀x/KA ( 1 - erf x/2√∝t)

where x is the depth of slab

∝ is the thermal diffusivity

t is time

A is area of the slab

k is the thermal conductivity

Ti is the initial temperature

Now for COPPER

thermal diffusivity ∝ is 11.23 × 10⁻⁵ m²/s = 120.88 × 10⁻⁵ ft²/s

thermal conductivity K = 386 W/m°C = 223.176 BTU/h.ft².°F

so

a) determine the surface temperature

Given that;

initial temperature Ti = 50°F and q₀ = 2000 BTU/h.ft², t = 55m = 55 × 60 = 3300

AT x = 0 ( surface )

so we substitute our values

T - 50 = [(2×2000√(120.88 × 10⁻⁵ × 3300)/π)) / 223.176] ×  esp( 0)

T - 50 = [(4000 × 1.1268) / 223.176] × 1

T - 50 =   20.1955

T = 50 + 20.1955

T = 70.196 °F

therefore the surface temperature is 70.196 °F

b)

at a depth of 2.5 ft i.e x = 2.5 ft

Error Function, exf = ( 2.5 / 2×√( 120.88 × 10⁻⁵ × 3300)

= erf( 0.62586 )

Error for function table erf( 0.62586 ) = 0.623897

now from our initial equation

T - Ti = (2q₀√(∝t/π))/KA exp( -x²/4∝t) -q₀x/KA ( 1 - erf x/2√∝t)

T - 50 = (2 × 2000√( 120.88×10⁻⁵×3300/π))/223.176 exp( 2.5²/ 4×120.88 × 10⁻⁵ × 3300)

=  2000×2.5 / 223.176 ×( 1 - 0.623897)

T = 58.426 °F

temperature at a depth of 2.5 ft, after 55 min is 58.426 °F

The rule requires the vast majority of new heavy truck tractors to achieve a 30 percent reduction in stopping distance compared to currently required levels. For these heavy truck tractors (approximately 99 percent of the fleet), the amended standard requires those vehicles to stop in not more than 250 feet when loaded to their gross vehicle weight rating (GVWR) and tested at a speed of 60 miles per hour (mph). For a small number of very heavy severe service tractors, the stopping distance requirement will be 310 feet under these same conditions. In addition, this final rule requires that all heavy truck tractors must stop within 235 feet when loaded to their “lightly loaded vehicle weight” (LLVW).

Explanation:

The time at which the acceleration is zero is given as 4.66 seconds

First we have to solve for the velocity. To do this, we would have to take the derivative.

\(s = e^-0.5t (3 t - 2)\)

Then velocity =

\(ds/dt = e^-0.5t (4 - 1.5 t)\)

The acceleration can be gotten by finding the second derivative

\(a = dv/dt = e^-0.5t (.75 t - 3.5)\)

To find t at acceleration = 0

We have

\(0 = e^-0.5t (.75t - 3.5)\)

This gives t to be

t = 4.66 sec

The displacement of a particle which moves along the s-axis isgiven by

s = (-2+3t)e^(-0.5t), where s is in meters and t is inseconds. Plot the displacement, velocity and acceleration versustime for the first 20 seconds of motion. Determine the time atwhich the acceleration is zero.

Note that the alterations have shifted the CG location.

CG location refers to the center of gravity location in an object or system, where the weight of the object or system is concentrated, and the balance is achieved.

To determine if the alterations caused the new empty weight CG to move, we need to calculate the new moment and the new CG location.

First, let's calculate the moment before the alterations:

Moment = Weight x Arm

Moment = 2,886 lb x 101.67378 in

Moment = 293,182.73 in-lb

Now, let's calculate the moment after the alterations:

Moment = Weight x Arm

Moment = (2,886 lb - 15 lb - 15 lb + 97 lb + 20 lb + 30 lb) x 71 in + 30 lb x 94 in

Moment = 2,958 lb x 71 in + 2,820 in-lb

Moment = 210,498 in-lb

Next, let's calculate the new empty weight:

New Empty Weight = 2,886 lb - 15 lb - 15 lb + 97 lb + 20 lb + 30 lb

New Empty Weight = 2,958 lb

Finally, let's calculate the new CG location:

New CG Location = New Moment / New Empty Weight

New CG Location = 210,498 in-lb / 2,958 lb

New CG Location = 71.06 in

Comparing the original CG location (101.67378 in) with the new CG location (71.06 in), we can see that the alterations have caused the new empty weight CG to move forward (toward the nose) of the aircraft.

Therefore, the alterations have shifted the CG location.

To keep the transistor at the edge of the ohmic region, the value of RD is calculated using Ohm's law, which states that current is equal to voltage divided by resistance.The equation that determines the RD value of a transistor in saturation mode is the following:

RD = (VDSQ - VDSsat)/ IDQ, where VDSQ is the DC voltage between the drain and the source terminals, VDSsat is the saturation voltage, IDQ is the DC current flowing through the transistor, and RD is the resistor connected to the drain terminal that limits the current through the transistor.In this case, the transistor's drain current is set at 3 mA, which is equal to the IDQ value. Therefore, the equation becomes:

RD = (VDSQ - VDSsat)/3 mAIf we assume that the transistor is operating in the ohmic region, then VDSQ is the supply voltage VDD, and VDSsat is zero. Thus, the equation simplifies to:RD = VDD/3 mAIf we set the drain current at 3 mA and assume that the transistor is operating in the ohmic region, then the RD value that keeps the transistor at the edge of the ohmic region is VDD/3 mA. This value depends on the supply voltage VDD and the physical properties of the transistor. The transistor's W/L ratio can be adjusted to achieve the desired value of IDQ and the corresponding RD value.
