Task 3 (LO3 P3.3, M3) A single-stage reciprocating compressor deals with V m3 of free air per hour at 1.01 15°C. The pressure and temperature in the cylinder during the suction stroke remain constant at P, bar and T, °C, respectively. The index of compression is n and delivery pressure is P2 bar Apply the first law of thermodynamics to calculate the power required to drive the compressor if the mechanical efficiency is 87% and clearance volume is negligible. Calculate the power required if the clearance volume is 5% (P33)

    A single acting compressor is required to deliver air at 60 bar from an induction pressure of 1 bar, at the rate of 3 m3/min measured at free air conditions of 1.013 bar and 15oC. The compression is carried out in two stages with an ideal intermediate pressure and complete intercooling. The clearance volume is 3% of the swept volume in each cylinder and the compressor speed 750 rev/min. The index of compression and re-expansion is 1.3 for both cylinders...
