Answer:
a) 
, b) 
, c) Irreversible.
Explanation:
a) The power input required by the refrigerator is:
b) The Coefficient of Performance of the refrigerator is:
c) The maximum ideal Coefficient of Performance of the refrigeration is given by the inverse Carnot's Cycle:
The refrigeration cycle is irreversible, as 
.
Answer:
Explanation:
The pressures given are relative
p1 = 2000 psi
P1 = 2014 psi = 13.9 MPa
p2 = 4 psi
P2 = 18.6 psi = 128 kPa
Values are taken from the steam pressure-enthalpy diagram
h2 = 2500 kJ/kg
If the output of the turbine has a quality of 85%:
t2 = 106 C
I consider the expansion in the turbine to adiabatic and reversible, therefore, isentropic
s1 = s2 = 6.4 kJ/(kg K)
h1 = 3500 kJ/kg
t2 = 550 C
The work in the turbine is of
w = h1 - h2 = 3500 - 2500 = 1000 kJ/kg
The thermal efficiency of the cycle depends on the input heat.
η = w/q1
q1 is not a given, so it cannot be calculated.

Answer:
B
Explanation:
only the radius of the circle as a result of shear strain change.
Answer:
D.) Transfer input energy from the power source throughout the machine.
Explanation:
Since the complex abnormalities of energy efficiency is depicted by the autonomy within self-operating machines, the correct answer is D.
