//Fluid system - By - Shiv Kumar
//Chapter 2 - Impact of Jet
//Example 2.16
clc
clear
//Given Data:-
Vi=18; //velocity of Jet at Inlet of, m/s
u=6; //Velocity of Vane, m/s
ui=u;
uo=u;
AoD=110; //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;
beta_o=beta_i;
//(a)
alpha_i=beta_i-asind(ui*sind(180-beta_i)/Vi); //degrees
Vwi=Vi*cosd(alpha_i); //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
Vrwo=Vro*cosd(beta_o); //m/s
Vwo=Vrwo-uo; //m/s
alpha_o=atand(Vfo/Vwo); //degrees
//(b)
alpha_o_dash=180-alpha_o; //degrees
//(c)
W=(Vwi+Vwo)*u/g; //N-m/N
//Results:-
printf("(a)Angle of Jet at Inlet of Vane, alpha_i=%.2f Degrees \n", alpha_i) //The answer vary due to round off error
printf(" Angle at Outlet of Vane, alpha_o=%.2f Degrees \n", alpha_o) //The answer vary due to round off error
printf("(b)Angle made by leaving Jet to the direction of motion of Vane, alpha_o_dash=%.2f Degrees \n", alpha_o_dash) //The answer vary due to round off error
printf("(c)Work done per second per unit weight of water striking the vane per second=%.2f N-m/N", W) //The answer vary due to round off error
