Determine the horsepower required to compress 1 lbm/min of ethylene oxide from 70 oF and 1 atm to 250 psia. The compressor has an efficiency of 75%. The molar heat capacity of ethylene oxide is given by Cp

Complete Question:

Problem 8 Determine the horsepower required to compress 1 lbm/min of ethylene oxide from 70 °F and 1 atm to 250 psia. The compressor has an efficiency of 75%. The molar heat capacity of ethylene oxide is given by

C_p=10.03+0.0184T  C_p[=]Btu/lbmole- "F ; T[=] °F C,

Explanation:

From the question we are told that:

Initial Temperature T_1=70 F

Final Temperature

Efficiency

Generally the equation for Work-done  is mathematically given by

Generally the equation for Efficiency  is mathematically given by

Since

Isotropic Power

Therefore

Since

Therefore
