Problem 6.18:

During a test of an air compressor, the following data were recorded: air at a flow rate of 50 mol/min was compressed from 1 bar and 25 °C to 10 bar. The temperature at the exit of the compressor was measured and found to be 450 °C.

a) What is the power (in kW) consumed by the compressor?

b) What is the efficiency of the compressor? Assume air to be an ideal gas with CP = 3.5R.

Problem 6.19:

Steam is compressed from 1 bar, 200 °C to 12 bar in a compressor operating at steady state.

a) Calculate the amount of work and the final temperature if compression is reversible.

b) Repeat the calculation if the efficiency of the compressor is 75% and report the lost work.
