Homework Statement
It is required to design a single acting twin cylinder air compressor to deliver 17.2kg/min of compressed air at 7.2 bar. The intake pressure and temperature are 1 bar and 15oC respectively. Compressor speed is to be 300 rpm. Take clearance volume as 5% of the swept volume. The stroke to bore ratio is 1.2 and assume n=1.3. Find the bore and stroke of the cylinder.
Homework Equations
Vc/Vs = 0.005
PV=mRT
volumetric efficiency = Va/Vs = (V1 - V4)/(V1 - V3)
The Attempt at a Solution
Firstly i try to find volumetric efficiency. However, V1, V3 and V4 still did not know.. so how...
