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 m³/kgm. The internal energy of the air leaving is 90 kJ/kgm and the air entering is 70 kJ/kgm. The coolant absorbs heat from the air at the rate of 58 kW. Determine the following: a) Change of Potential Energy in kJ/s b) Change in Kinetic Energy in kJ/s c) Change in Internal Energy in kJ/s
