Methane (CH4) enters a compressor operating at steady state with a mass flow rate of 170 lbm/hr. The methane enters the compressor at p1 = 15 lbf/in2 , T1 = 80F and exits at p2 = 100 lbf/in2 . The work input to the compressor is 15 hp. Assume ideal gas behavior for the methane with constant specific heats (cp = 0.538 Btu/lbm·R, cv = 0.414 Btu/lbm·R). Kinetic and potential energy effects are negligible and the compressor is insulated

1)Determine the temperature at the exit of the compressor, in F.

2) Determine the rate of entropy production, Btu/hr·R, in the compressor
