+//INPUT DATA

+pa=1;//ambient pressure in bar

+ta=15;//temperature in Degree C

+ps1=0.98;//ambient pressure in bar

+ts1=30;//temperature in Degree C

+c=0.04;//clearance

+N=500;//speed in rpm

+p1=1;//ambient pressure

+p2=5;//discharge pressure

+n=1.3;//for cylinders

+

+//CALCULATIONS

+

+//Suction and ambient conditions are same

+vs=0.04*2*N;//swept volume in m^3/min

+nv=1+c-(c*(p2/p1)^(1/n));//volumetric efficiency in percentage

+v14=nv*(vs)/60;//volume in m^3/sec

+ip=(n/(n-1))*p1*100*(v14)*((p2/p1)^((n-1)/n)-1);//indicated power in kJ/min

+

+//Suction and ambient conditions are different

+nv1=1+c-(c*(p2/ps1)^(1/n));//volumetric efficiency in percentage

+v141=nv1*(vs)/60;//volume in m^3/sec
