+//Given Data:-
+        d=25;      //Diameter of the Jet, mm
+        V=27;     //Velocity of the Jet, m/s
+        AoD=140;       //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
+       m=rho*a*V;         //Mass Flow Rate, kg/s
+   //For condition of Maximum work done,
+       u=V/3;        //Velocity of Vane, m/s
+       theta=180-AoD;          //degrees
+   //(a)Maximum work done/second
+       W=rho*a*(V-u)^2*(1+cosd(theta))*u/1000;       //kJ/s
+   //(b)Efficiency of the Jet,
+       KE=(1/2)*rho*a*V^3;        //kinetic energy supplied by jet per second, J
+       eta=W*1000/KE*100;         //In percentage
+
+//Result:-
+     printf("(a)Maximum work done/sec=%.3f kJ/s \n", W)      //The answer vary due to round off error
+     printf("(b)Effeciency of the Jet, eta=%.2f percent \n", eta)      //The answer vary due to round off error
