A two stage reciprocating air compressor consists of four cylinders having the same bore and stroke. Three cylinders are used for the low pressure stage, and one cylinder is used for the high pressure stage. The delivery pressure is 7 bar absolute and the FAD is 4.2 m3/min. Air is drawn in at 1.013 bar absolute and 15 °C and an intercooler cools the air to 38 °C. The index of compression is 1.3 for all four cylinders. Neglecting clearance calculate: (a) the intermediate pressure; (8 marks) (b) the power required to drive the compressor (7 marks) (c) the isothermal efficiency (5 marks)
