+//Example 2.9

+//Given Data:-
+        d=65;     //Diameter of the Jet, mm
+        V=20;     //Velocity of the Jet, m/s
+        u=8;      //Velocity of curved vane, m/s
+        AoD=160;     //Angle of Deflection, degrees
+
+//Data Used:-
+     rho=1000;     //Density of water, kg/m^3
+
+//Computations:-
+        d=d/1000;       //m
+        a=(%pi/4)*d^2;      //cross-sectional area of Jet, m^2
+        theta=180-AoD;      //degrees
+        Fx=rho*a*(V-u)^2*(1+cosd(theta));      //N
+        P=Fx*u/1000;       //Power of Jet, KW
+        KE=(1/2)*rho*a*V^3;     //Kinetic energy of Jet per second, N-m/s(W)
+        eta=P*1000/KE*100;     //In percentage
+        
+//Results:-
+     printf("(a)The Force exerted on plate in direction of Jet, Fx=%.2f N  \n", Fx)      //The answer vary due to round off error
+     printf("(b)Power of Jet=%.3f KW  \n", P)      //The answer vary due to round off error
+     printf("(c)Efficiency of Jet, eta=%.2f percent", eta)
