Find required work input per kg of air and exit temperature

1. The adiabatic compressor of a large gas turbine receives air from the ambient surroundings at 95 kPa and 20°C with a low (negligible) velocity. At the compressor discharge, air exits at 1.52 MPa and 430°C with velocity of 90 m/s. The power input to the compressor is 5000 kW. Determine the mass flow rate of air through the unit.

2. Air enters a compressor at 100 kPa and 300 K and is compressed to 150 kPa. The efficiency is 70%. What is the required work input per kg of air? What is the exit temperature?
