+//Input data

+V1=0.05;//displacement of a piston of a single cylinder single stage reciprocating compressor in m^3

+P1=1;//pressure of air sucked in the compressor in bar

+T1=300;//Initial Temperature of air in K

+P2=7;//Pressure after the compression process in bar

+

+//Calculations

+V2=(P1*V1)/P2;//Volume after the compression in m^3

+W1=P1*10^5*V1;//Work done by air during suction in Nm

+W2=P1*10^5*V1*log(V2/V1);//Work done on sir during isothermal compression in Nm

+H=-W2;//Heat transferred to the cylinder walls in Nm or J

+W3=P1*10^5*V1;//Work done on air during delivery in Nm

+Wn=W1+(-W2)-W3;//Net work done during the cycke in N m

+

+//Output
