- 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 and the temperature at the end of the induction stroke in each cylinder is 30oC. The mechanical efficiency of the compressor is 87%. Calculate:
- The indicated power required;
- The saving in power over single-stage compression between the same pressures;
- The swept volume of each cylinder;
The required power output of the drive motor
