Two stage reciprocating compressor has cylinder of diameter or bore450mm and 300mm stroke length. Clearance volume is 5 percent of stroke volume of cylinder. It takes air at the rate of 0.2  m3/intake pressure and temperature of first stage compressor is 0.1 KNm-2 and 16 0C respectively .Pressure at the exit of 2nd stage compressor is 0.7 KNm-2.And compressor runs at 10 rev/sec.Determine

a)     Volumetric Efficiency
b)     Total volume of the cylinder
c)     Overall pressure ratio
d)     Draw graphical relationship between overall pressure ratio and volumetric efficiency?
