+//Given Data:-
+ P=3000; //Power developed, kW
+ H=300; //Head, m
+ N=375; //Speed, rpm
+ eta_O=83/100; //Overall efficiency
+ Ku=0.46; //Speed ratio
+ Cv=0.98; //Co-efficient of Velocity
+
+//Data Used:-
+ rho=1000; //Density of water, kg/m^3
+ g=9.81; //Acceleration due to gravity, m/s^2
+
+//Computations:-
+ //(i) Diameter of Turbine, D

+ d=(Q/((%pi/4)*Vi))^(1/2); //m

+//Results:-
