Air enters a compressor at a pressure of 1.0 bar and exits at 8.5 bar. The compressor inlet temperature is 37 °C. The compressor is not insulated. Kinetic and potential energy effects can be neglected. The compressor outlet temperature is 650 K and the power input to the compressor is 500 kW. The compressor is operating at steady-state, and the air can be modeled as an ideal gas. The air mass flow rate through the compressor is 1.8 kg/s. a. Determine the direction and rate of heat transfer, in kJ/kg. b. Determine the compressor isentropic efficiency. c. Draw the process on a T-s diagram (clearly indicate the direction of the process and label the states) d. Determine the entropy generation rate, in kJ/kg/K, assuming the boundary temperature is 100 °C, and state the nature of the process (reversible, irreversible, or impossible). Summarize you results in the table below a. heat transfer, kJ/kg (include direction, so in or out?) b. isentropic efficiency d. entropy generation rate, in kJ/kg/K, and is it reversible, irreversible, or impossible?
