A compressor draws in 0.25 m³/s of air whose density is 1.26 kg/m³ and discharges it with a density of 4.87 kg/m³. At the suction, p, = 103.4 kPaa; at discharge, P₂ = 551.4 kPaa. The increase in the specific internal energy is 78.63 kJ/kg, and the heat from the air by cooling is 30.24 kJ/kg. Neglecting changes of potential and kinetic energy, determine the work done on air in kW, Btu/min, and Hp. [Ans. 44.11 kW, 2508.6 Btu/min, 59.13 Hp]

![A compressor draws in 0.25 m³/s of air whose density is 1.26 kg/m³ and discharges
it with a density of 4.87 kg/m³. At the suction, p, = 103.4 kPaa; at discharge,
P₂=551.4 kPaa. The increase in the specific internal energy is 78.63 kJ/kg, and
the heat from the air by cooling is 30.24 kJ/kg. Neglecting changes of potential
and kinetic energy, determine the work done on air in KW, Btu/min, and Hp.
