Thedelivery pressure of a two
stage compressor is 17.5 bar and theclearance volume of lp cylinder
is equal to 4% of swept volume. theatmospheric conditions are 1 bar
and 288 k. the starting pressurein lp cylinder is 1 bar and temp.
at the beginning of compressionin each stage is 326 k and the
intercooler pressure is 4 bar. theindex of polytropic law of
compression and expansion in both thestages is 1.25. determine
volumetric efficiency, work done
perkg of air and isothermal
