Question - A compressor draws in 0.5 kg_m/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/kg_m. The internal energy of the air leaving is 90 kJ/kg_m and the air entering is 70 KJ/kg_m. 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

d) Change in Work Flow in KJ/s

e) Work in KW

f) Work is done on the system or Work is done by the system?
