//Input data
a=17//Nozzle angle in degrees
Vb=125//Blade velocity in m/s
b2=22//Blade angle n degrees
a1=26//Blade angle n degrees
b4=30//Blade angle n degrees
f=0.9//Friction factor
a2=90//Axial angle in degrees
//Calculations
dVw=1040//Velocity in m/s from Velocity triangles Fig. E.7.14
V1=575//Velocity in m/s from Velocity triangles Fig. E.7.14
V4=75//Velocity of steam exiting stage in m/s from Velocity triangles Fig. E.7.14
WD=(dVw*Vb)/1000//Diagram work in kJ/kg
nd=((WD*1000)/((1/2)*V1^2))*100//Diagram efficiency in percent
//Output
