A compressor draws in 0.5 kgm/s of air with 7 m/s speed, 100 kPa pressure, and 0.95 m3/kgm. The air leaves at 5 m/s, 700 kPa and 0.19 m/kgm- The internal energy of the air leaving is 90 kJ/kgm greater than that of the air entering. The coolant absorbs heat from the air at the rate of 58 kW. Determine the work in kW.

A compressor draws in 0.5 kgm/s of air with 7 m/s speed, 100 kPa pressure, and 0.95 m³/kgm. The air leaves at 5 m/s, 700 kPa and 0.19 m/kg,m. The internal energy of the air leaving is 90 kJ/kgm greater than that of the air entering. The coolant absorbs heat from the air at the rate of 58 kW. Determine the work in kW.
