QUESTION 1-Reciprocating air compressor A two-stage, single-acting, reciprocating compressor delivers 0,07m³ free air per second. Free air conditions are 101.325 kPa and 15°C. Intake conditions are 95 kPa and 22°C. Delivery pressure from the compressor is 1300 kPa. The intermediate pressure is ideal and there is perfect intercooling. The compression index is 1.25 in both cylinders. The overall mechanical and electrical efficiency is 75%. Neglecting clearance, Calculate: 1.1 The energy input to the driving motor. (11) 1.2 The percentage saving in work by using the two-stage intercooled compressor instead of using a single-stage compressor to achieve the same delivery. (7) [18]
