+//INPUT DATA
+C1=600;//Steam velocity in m/s
+b1=30;//Blade angle at inlet in first stage in degrees
+b2=30;//Blade angle at exit in first stage in degrees
+b3=30;//Blade angle at inlet in second stage in degrees
+b4=30;//Blade angle at exit in second stage in degrees
+a4=90;//Nozzle angle in second stage in degrees
+m=3;//Mass of steam in kg/s
+x=15;//Length for drawing velocity triangle in mm
+y=56;//Length of BC from the velocity triangle in mm
+
+//CALCUALTIONS
+C1n=C1/y;//Velocity of steam in m/s
+U=x*C1n;//Blade speed in m/s
+l=103;//Length from velocity triangle in mm
+P=(m*l*C1n*U)/1000;//Power developed in kW
+
+//OUTPUT
+mprintf('Blade speed is %3.1f m/s \n Power developed by the turbine is %3.2f kW',U,P)
