Air enters a compressor at 100 kPa and 27 oC and exits at 700 kPa and 227 oC. The compressor is adiabatic and the volumetric flow rate at the exit of the compressor is 17 L/s. For this compressor changes in kinetic and potential energies are negligible. If the compressor operates at steady state, find the input power to the compressor in kW.

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
