+//Fluid system - By - Shiv Kumar
+//Chapter 4 - Pelton Turbine (Impulse Turbine)
+//Example 4.1

+     clear
+     
+//Given Data:-
+        P=735.75;     //Power Developed, kW
+        H=200;        //Head, m
+        N=800;         //Speed, rpm
+        eta_O=86/100;     //Overall Efficiency
+        d_by_D=1/10;      //Ratio of Jet diameter to turbine diameter (d/D)
+        Cv=0.98;         //Co-efficienct of velocity
+        Ku=0.45;      //Speed ratio
+
+//Data Used:-
+     rho=1000;     //Density of water, kg/m^3
+     g=9.81;        //Acceleration due to gravity, m/s^2
+
+//Computations:-
+        Q=P*1000/(rho*g*H*eta_O);          //Net discharge, m^3/s
+   //(a)Diameter of Turbine, D
+        D=60*Ku*sqrt(2*g*H)/(%pi*N);        //m
+        d=D*d_by_D;                   //m
+   //(b)The no. of Jets required
+        q=(%pi/4)*d^2*Cv*sqrt(2*g*H);          //Discharge of a single Jet, m^3/s
+        n=round(Q/q);              //No. of Jets
+   //(c)Diameter of Jet, d
+        d=d_by_D*D;                 //m
+
+//Results:-
+     printf("(a)Diameter of Turbine, D=%.4f m  \n", D)    //The answer vary due to round off error
+     printf("(b)The number of Jets required, n=%.f  \n", n)
+     printf("(c)Diameter of Jet, d=%.4f m  \n", d)
