Find out the value of C.O.P. for the given values of enthalpies. h1 = 1126.25 kJ/kg h4 = 250.25 kJ/kg W = 120 kJ/kg

Find out the value of C.O.P. for the given values of enthalpies. h1 = 1126.25 kJ/kg h4 = 250.25 kJ/kg W = 120 kJ/kg Correct Answer 7.3

Refrigerating effect = h1 − h4 = 1126.25 − 250.25 = 876 kJ/kg Work = 120 kJ/kg C.O.P. = Refrigerating effect / Work done = 876 / 120 = 7.3.
