+//INPUT DATA
+p1=1;//pressure in bar
+n=1.2;//constant
+N=100;//speed in rpm
+Rp=6;//compression ratio at constant pressure
+aps=150;//average piston speed in m/min
+ip=50;//indicated power in kW
+
+
+//CALCULATIONS
+pm=p1*(n/(n-1))*((Rp^((n-1)/n))-1);//Mean effective pressure in bars
+a=ip*60/(pm*10^2*150);//size of the cylinder in m^2
+d=sqrt(a*4/3.14);//size of the cylinder in m^2
+l=150/(2*N);//size of the cylinder in m^2
+
+//OUTPUT
+printf('(i)size of the cylinder is d %3.4f m \n  l %3.2f m',d,l)
