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 = 80F 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

Question
Methane gas (CH4) enters a home heating furnace operating at
steady state and burns completely with 110% of theoretical dry air,
each stream entering at 77 F, 1 atm. Combustion products are
discharged to the flue at 300 F, 1 atm. Return air from the house
enters at 60 F, 1 atm, with a volumetric flow rate of 1000 ft3 /min
and is supplied to heat the house at 120 F, 1 atm. Kinetic and
potential energy effects can...

An air compressor is operating at a steady state. The air enters
at with a volumetric flow rate 1.2 m^3/s at 170 kPa and 22 degrees
celsius with negligible velocity and leaves at 1500 kPa with
velocity of 200 m/s. The power to the compressor is 60 kW and the
compressor is cooled at a rate of 15 kJ/kg. Determine the exit
