Question

Can someone please help me with this? I am desperate right now, I need any help you can offer. Please, anything....

An adiabatic R-22 compressor has an inlet state 4 bar, -5 degree C(hin = 248.6 kj/kg); sin = .9411 kj/kg k) and an outlet pressure of 20 bar. The isentropic compressor efficiency is 82.3%. Find the exit temperature of an isentropic (ideal) compressor from the same inlet state to the same exit pressure. (USE NEAREST TABLE VALUES) 51.3 degree C 70 degree C 80 degree C 90 degree C Find the exit temperature of the specified compressor. (USE NEAREST TABLE VALUES) 51.3 degree C 70 degree C 80 degree C 90 degree C Find the power required to compress 1.2 kg/s of refrigerant in the actual compressor. (Sign convention) -16.1 kW -50.6 kW -61.4 kW -82.5 kW Find the rate of entropy production for the flow in part c. 0.033 kW/k 33 kW/k 0.102 kW/k 29.3 kW/k
