//Given Data:-
V1=40; //Velocity of the Jet at Inlet, m/s
V2=32; //Velocity of the Jet at Outlet, m/s
theta=65; //Angle of Deflection from original direction, degrees
m=0.9; //Mass flow rate, kg/s
//Computations:-
Fx=m*(V1-V2*cosd(theta)); //N (Answer in textbook is wrong)
Fy=m*V2*sind(theta); //N
F_R=sqrt(Fx^2+Fy^2); //Resultant Force, N
phi=atand(Fy/Fx); //Angle made by resultant with X-axis, degrees
//Results:-
printf("Resultant Force, F_R=%.2f N at an angle, phi=%.2f Degrees to X-axis", F_R, phi) //The answer provided in the textbook is wrong
