3. Please solve with complete and detailed solutions. Thankyou!

An air compressor handles 8.5 m/min of with a density of 1.26 kg/m' and a pressure of 1
atm, and it discharges at 445 kPa (gage) with a density of 4.86 kg/m. The change in
specific internal energy across the compressor is 82 kJ/kg, and the heat loss by cooling is 24
kJ/kg. Neglecting changes in kinetic and potential energies, find (a) the work in kJ/kg and
(b) the power in kW.
