Answer:
Pump factor = Fp = 7.854 gal/cycle
Ev = 82.00 %
P_H = 183.29 hp
Explanation:
Given data:
Dimension of duplex pump
6.5 inch liner
2.5 inch rod
18 inch strokes
Pressure 3000 psig
Pit dimension
7 ft wide
20 ft long
Ls = 18 inch
Velocity = (18)/10
volumetric efficiency is given as E_v = (Actual flow rate)/(Theortical flow rate) * 100
we know that flow rate is given as = Area * velocity
Theoritical flow rate 

Ev = 82.00 %
Pump factor 

Fp = 1814.22 in^3/cyl
Fp = 7.854 gal/cycle
Flow rate 
Power 
Answer:
Ps=19.62N
Explanation:
The detailed explanation of answer is given in attached files.
Answer:
A) 
B) 
C) Second law efficiency 4.85%
exergy destruction for the cycle = 9.3237 kW
Explanation:
Given data:
degree celcius
degree celcius

Power to refrigerator = 9.8 kW
Cp = 3.35 kJ/kg degree C




b)

wil be max when COP maximum
taking surrounding temperature T_H = 20 degree celcius

we know that


c) second law efficiency

exergy destruction os given as 
= 9.8 - 0.473 = 9.3237 kW
