1. A single stage single acting air compressor delivers 14m³ of free air per minute from 1bar to 7 bars. The speed of air compressor is 310 rpm and compression and expansion follows PV1.35 = c. Clearance volume is 5% of the piston displacement. Find out diameter or the bore and stroke (d x L) of the compressor if L = 1.5d.

2. An ideal single stage air compressor without clearance takes air at 100 kPa
with temperature of 16 °C and delivered at 413 kPa after isentropic
compression. What is the work done by the compressor in kJ/kg?
