2. Nitrogen (N2) enters an insulated compressor operating at steady state at 100 kPa, 37C with a mass flow rate of 1000 kg/h and exits at 1 MPa. Kinetic and potential energy effects are negligible. The nitrogen can be modeled as an ideal gas with k = 1.391. a) Determine the minimum theoretical power input required, in kW, and the corresponding exit temperature, in C. b) If the exit temperature is 397C, determine the power input, in kW, the isentropic compressor efficiency, and the rate of entropy generation, in kW/K, in part (b)
