+
+//INPUT DATA
+m=3;//Mass flow rate of steam in kg/s
+C1=425;//Steam velocity in m/s
+r=0.4;//Ratio of blade speed to jet speed
+W=170;//Stage output in kW
+IL=15;//Internal losses in kW
+a1=16;//Nozzle angle in degrees
+b2=17;//Blade angle at exit in degrees
+W1=265;//Relative velocity at inlet from the velocity triangle in m/s
+W2=130;//Relative velocity at outlet from the velocity triangle in m/s
+
+//CALCULATIONS
+U=C1*r;//Blade speed in m/s
+P=(W+IL)*1000;//Total power developed in W
+Cx=P/(m*W);//Change in whirl velocity in m/s
+ndia=((2*U*Cx)/(C1^2))*100;//Blading efficiency
+Wr=W2/W1;//Blade velocity co-efficient
+
+//OUTPUT
+mprintf('Blading efficiency is %3.1f percent \n Blade velocity co-efficient is %3.2f',ndia,Wr)
