+//INPUT DATA
+C1=375;//Steam velocity in m/s
+a1=20;//Nozzle angle
+U=165;//Blade speed in m/s
+m=1;//Mass flow rate of steam in kg/s
+Wr=0.85;//Blade friction factor
+Ca1=130;//Axial velocity at inlet from the velocity triangle in m/s
+Ca2=Ca1;//Axial velocity at outlet in m/s
+W1=230;//Relative velocity at inlet from the velocity triangle in m/s
+Cx=320;//Change in whirl velocity from the velocity triangle in m/s
+
+//CALCULATIONS
+b2=41;//Blade angle at exit from the velocity triangle in degrees
+b1=34;//Blade angle at exit from the velocity triangle in degrees
+W=(m*Cx*U)/1000;//Power developed by turbine in kW
