hello your question is incomplete attached below is the missing part and also attached is the solution

answer: a) 0.4801

              b) 5.398 kw

              c) 2.14

              d) 12.72

Explanation:

The quality of the refrigerant at the evaporator inlet

h4 = hf4 + x4(hfx4)

Refrigeration load

Ql = m(h1-h4)

COP of the refrigerator

Ql / m(h2-h1) - Qm

Theoretical maximum refrigeration load

( Ql )max = COPr.rev * [m(h2-h1) - Qin]

The quality that will exist at the inlet of the refrigerant's evaporator would be:

a). \(0.4801\)

The load of the refrigeration would be          

b). \(5.398 kW\)

The refrigerator's COP would be:

c). \(2.14\)

The maximum refrigeration load would be as follows:          

d) \(12.72\)

a). The determination of the quality of the refrigerant at the inlet of the evaporator would be:

\(h4 = hf_{4} + x_{4}(hfx_{4})\)  

As given,

\(hf_{4}\) \(= 3.841\)

\(hf_{2,4}\)\(= 223.95\)

\(h_{4} = 111.37\)

Now,

solving for \(x_{4}\) \(= (111.37 - 3.841)/223.95\)

\(= 0.4801\)

b). Refrigeration load

\(Q_{l}\) \(= m(h_{1} - h_{4})\)

\(= 0.0455(230.01-111.37)\)

\(= 5.398 kW\)

c). COP of the refrigerator

\(Q_{l}\)/\(m(h_{2} - h_{1}) - Q_{m}\)

by putting the values, we get

∵ COP \(= 2.14\)

d). Theoretical maximum refrigeration load

\((Q_{l})\)max \(= COPr.rev\) × \({m(h_{2} - h_{1}) - Q_{in}\)

by putting the values, we get

∵ \(Q_{L}max = 12.72\)

Explanation:

L = 0.964

For an M/G/1 system with λ = 20, μ = 35, and σ = 0.005, the average number in the system is L = 0.4286. The correct answer is option D.

To find the average number in the system for an M/G/1 system with λ = 20, μ = 35, and σ = 0.005, we can use Little's Law, which states that the average number in the system is equal to the average arrival rate (λ) divided by the service rate (μ) minus the average service time (1/μ).

First, we need to find the average service time, which is the reciprocal of the service rate: 1/μ = 1/35 = 0.0286.

Next, we can plug in the values for λ and μ into Little's Law:

L = λ/(μ-λ*0.0286)
L = 20/(35-20*0.0286)
L = 0.4286

Therefore, the answer is D. L = 0.4286.

Please note that the correct answer may depend on specific assumptions and formulas used in the context of the M/G/1 system.

Therefore option D is correct.

Logistic regression is important in predicting the probability of successful completion of an MBA program based on undergraduate GPA and GMAT score.

Logistic regression is a valuable statistical technique for predicting the probability of an event occurring when the outcome is binary, such as in this case where we want to determine the likelihood of successful completion of an MBA program. By using undergraduate GPA and GMAT score as independent variables, logistic regression can help us assess the impact of these factors on the probability of success.

The logistic regression model estimates the relationship between the predictors (GPA and GMAT score) and the binary outcome (successful completion or not) by fitting a logistic function to the data. It calculates the odds of success based on the values of the predictors and transforms these odds into probabilities.

In this scenario, the director of graduate studies can use logistic regression to understand how undergraduate GPA and GMAT score contribute to the probability of a student successfully completing the MBA program. By analyzing the model's coefficients, they can identify which variable has a stronger influence on the outcome and make informed decisions regarding admissions and program support.

Answer:

Explanation:

This problem involves projectile motion, and we can use the equations of motion to find the various quantities asked for:

i) Equation of path followed by bomb:

The path of the bomb is given by the vector equation r = (50t)i + (4t^2)j, where i and j are unit vectors in the x and y directions, respectively. We can rewrite this equation in terms of x and y coordinates by substituting i = (1, 0) and j = (0, 1), which gives:

x = 50t

y = 4t^2

Therefore, the equation of the path followed by the bomb is y = (1/100)x^2.

ii) Time taken to reach the ground:

The bomb will reach the ground when its height above the ground (y-coordinate) becomes zero. So we can set y = 0 and solve for t:

0 = 4t^2

t = 0 or t = sqrt(0) = 0

This means the bomb will hit the ground at t = 0 and stay on the ground afterwards.

iii) Horizontal distance traversed by the bomb:

The horizontal distance traversed by the bomb is equal to the displacement in the x-direction, which is given by:

Δx = x(final) - x(initial) = 50t - 50(0) = 50t

At t = 0 (when the bomb hits the ground), Δx = 0. Therefore, the bomb travels a horizontal distance of 50t before hitting the ground.

iv) Displacement, velocity and acceleration at t=5sec:

At t=5sec, we can find the displacement of the bomb by substituting t=5 into the vector equation of the path:

r(5) = (50(5))i + (4(5^2))j = 250i + 100j

Therefore, the displacement of the bomb at t=5sec is 250i + 100j.

To find the velocity and acceleration at t=5sec, we can differentiate the vector equation of the path with respect to time:

v = dr/dt = (50)i + (8t)j

a = d^2r/dt^2 = 0i + 8j

Substituting t=5 into these equations, we get:

v(5) = (50)i + (8(5))j = 50i + 40j

a(5) = 0i + 8j

Therefore, the velocity of the bomb at t=5sec is 50i + 40j, and the acceleration is 8j.

v) Tangential and normal component of acceleration at t=5 sec:

The acceleration at t=5sec is 8j. The tangential component of acceleration is zero, since the velocity vector is purely horizontal at this time. The normal component of acceleration is equal to the magnitude of the acceleration vector, since it is perpendicular to the velocity vector. Therefore, the tangential component of acceleration is zero, and the normal component of acceleration is 8 m/s^2.

Answer:

The resulting pressure of the gas when its volume decreases is 300 kN/m².

Explanation:

Given;

initial volume of the gas, V₁ = 80 L

number of moles of the gas, n = 0.5 moles

initial pressure of the gas, P₁ = 150 kN/m² = 150 kPa

Determine the constant temperature of the gas using ideal gas equation;

PV = nRT

where;

R is ideal gas constant = 8.315 L.kPa/K.mol

T is the constant temperature

\(T = \frac{P_1V_1}{nR} \\\\T = \frac{150.kPa \ \times \ 80 .L}{0.5 .mol \ \times \ 8.315(L.kPa/mol.K)} \\\\T = 2,886.35 \ K\)

When the gas is compressed to half of its volume;

new volume of the gas, V₂ = ¹/₂ V₁

                                             = ¹/₂ x 80L = 40 L

The new pressure, P₂ is calculated as;

\(P_2V_2 = nRT\\\\P_2 = \frac{nRT}{V_2} \\\\P_2 = \frac{0.5 \times 8.315\times 2886.35}{40} \\\\P_2 = 300 \ kPa = 300 \ kN/m^2\)

Therefore, the resulting pressure of the gas when its volume decreases is 300 kN/m².

Cold solvent cleaning is a process used to remove grease, wax and other impurities from metal and other parts. The process is also called degreasing or parts washing.

Explanation:

Air enters the compressor at 100 kpa and 300 k and is compressed to 1000 kpa, thermal efficiency of the Brayton cycle with reheat and regeneration is approximately 3.1%.

These steps can be used to calculate the thermal efficiency of the Brayton cycle with reheat and regeneration:

γ = cp / cv

For air, cp = 1005 J/(kg·K) and cv = 718 J/(kg·K)

γ = 1005 / 718 ≈ 1.4

Efficiency of the compressor (η_comp):

η_comp = (P2 / P1)^((γ - 1) / γ)

where P1 = 100 kPa (inlet pressure) and P2 = 1000 kPa (outlet pressure)

η_comp = (1000 / 100)^((1.4 - 1) / 1.4) ≈ 0.585

Efficiency of the turbine (η_turbine):

η_turbine = (T3 / T4)^((γ - 1) / γ)

where T3 = 1400 K (inlet temperature of the first turbine stage) and T4 = 1400 K (reheat temperature)

η_turbine = (1400 / 1400)^((1.4 - 1) / 1.4) ≈ 1.000 (isentropic expansion)

Efficiency of the regenerator (η_regenerator):

η_regenerator = 1 - (1 / effectiveness)

where the effectiveness of the regenerator = 95%

η_regenerator = 1 - (1 / 0.95) ≈ 0.053

Calculate the thermal efficiency (η_cycle) of the entire Brayton cycle:

η_cycle = η_comp * η_turbine * η_regenerator

η_cycle = 0.585 * 1.000 * 0.053 ≈ 0.031 (or 3.1%)

Thus, the thermal efficiency of the Brayton cycle with reheat and regeneration is approximately 3.1%.

the mole fraction of acetone in the outlet liquid is determined as follows:

solute from Basis Gas flow rate \(G_s = 10(1-0.012) =9.88 kmol/hr\)

Let the entering mole be :\(y_1 = 1.2\) % = 0.012

\(y_1 =(\dfrac{y_1}{1-y_1})\)

\(y_1 =(\dfrac{0.012}{1-0.012})\)

\(y_1 =0.012\)

\(y_2 = 0.001\)

Thus; the mole fraction of acetone in the outlet liquid is:

\(G_s y_1 + L_s x_2 = y_2 L_y + L_s x_1\)

\(9.88(0.012-0.001)=15*x_1\)
