Question: An air compressor operating at steady state receives air at 100 kPa and 25oC. The ratio of pressure at the exit to that at inlet

An air compressor operating at steady state receives air at 100 kPa and 25oC. The ratio of pressure at the exit to that at inlet is 5. There is no significant heat transfer between the compressor and its surroundings. Also changes in ke and pe are negligible. If the isentropic compressor efficiency is 75 %, determine.
(a) The actual power.
(b) Temperature at the compressor exit. Use the PG model for air.
