Re-Solve Problem 8-61 in your text book using EES.

1. Determine the power input to the compressor, the isentropic efficiency of the compressor, the minimum possible power input, the second law efficiency, the irreversibility rate.

2. Study the effect of varying the compression inlet temperature from -16 to -36 oC. Plot the actual power input, the second law efficiency and the irreversibility rate as a function of the inlet temperature.
