+//INPUT DATA
+p1=1;//initial pressure in bar
+pd=9;//delivery pressure in bar
+n=1.3;//index of compression
+R=0.287;//gas constant
+t1=300;//temperature in K
+m=1;//mass of air
+cp=1.005;//specific pressure
+
+//CALCULATIONS
+p2=sqrt(p1*pd);//intermediate pressure in bar
+wd=2*((n/(n-1))*R*t1*(((pd/p1)^((n-1)/(2*n)))-1));//minimum work done per min
+t2=t1*((p2/p1)^((n-1)/n));//temperature K
+Qr=m*cp*(t2-t1);//heat rejected to intercooler in kJ/kg

+//OUTPUT
+printf('(i)minimum work done per min %3.2f kJ/kg \n (ii)%3.4f kJ/kg ',wd,Qr)
