//Chapter 2 - Impact of Jet
//Example 2.18

//Given Data:-
Vi=18; //velocity of Jet at Inlet of, m/s
u=6; //Velocity of Vane, m/s
ui=u;
uo=u;
AoD=120; //Angle of deflection of the Jet, degrees
//Data Used:-
g=9.81; //Acceleration due to gravity, m/s^2
//Computations:-
beta_i=(180-AoD)/2; //degrees
beta_o=beta_i;
//(i)
alpha_i=beta_i-asind(ui*sind(180-beta_i)/Vi); //degrees
//(ii)
Vrwi=Vi*cosd(alpha_i)-ui; //m/s
Vfi=Vi*sind(alpha_i); //m/s
Vri=Vfi/sind(beta_i); //m/s
Vro=Vri;
Vfo=Vro*sind(beta_o); //m/s
Vwo=Vro*cosd(beta_o)-uo; //m/s
alpha_o=atand(Vfo/Vwo); //degrees
Vo=Vfo/sind(alpha_o); //m/s
//(iii)
W=(Vi*cosd(alpha_i)+Vwo)*u/g; //N-m/N
//Results(a):-
printf("(i)Angle of Jet at Inlet, alpha_i=%.2f Degrees \n", alpha_i)
printf("(ii)Absolute velocity of Jet at Outlet, Vo=%.2f m/s with angle alpha_o=%.2f Degrees \n", Vo,alpha_o) //The answer vary due to round off error
printf("(iii)Work done per N of Water=%.2f N-m/N", W) //The answer vary due to round off error
