//Chapter 2 - Impact of Jet
//Example 2.11
clc
clear
//Given Data:-
//(a)
V=60; //Velocity of the Jet, m/s
theta=30; //Angle of Outlet, degrees
//(b)
u=25; //Velocity of vane, m/s
//Data Used:-
g=9.81; //Acceleration due to gravity, m/s^2
//Computations:-
//(a)
Fx=(V/g)*(1+cosd(theta)); //Force exerted by Unit weight of water in direction of Jet, N/N of Water
Fy=V*sind(theta)/g; //Force exerted by Unit weight of water in direction perpendicular to direction of Jet, N/N of Water
F_R=sqrt(Fx^2+Fy^2); //Resultant for per unit weight of water, N/N of Water
phi=atand(Fy/Fx); //Angle made by resultant with X-axis, degrees
//Results(a):-
printf("(a)\nForce exerted by Unit weight of water in direction of Jet, Fx=%.2f N/N of Water \n", Fx)
printf("Force exerted by Unit weight of water in direction perpendicular to direction of Jet, Fy=%.2f N/N of water \n", Fy) //The answer vary due to round off error
printf("Resulatant Force, F_R=%.2f N/N of Water at angle, phi=%.2f degrees \n\n", F_R, phi) //The answer vary due to round off error
//(b)
Fx=(V-u)*(1+cosd(theta))/g; //Force exerted by Unit weight of water in direction of Jet, N/N of Water
Fy=(V-u)*sind(theta)/g; //Force exerted by Unit weight of water in direction perpendicular to direction of Jet, N/N of Water
F_R=sqrt(Fx^2+Fy^2); //Resultant force per unit weight of water, N/N of Water
phi=atand(Fy/Fx); //Angle made by resultant with X-axis, degrees
W=Fx*u; //N-m/s/N of Water
P=Fx*u/1000; //Power developed per unit weight of water, KW/N of Water
//Result(b)
printf("(b)\nForce exerted by Unit weight of water in direction of Jet, Fx=%.2f N/N of Water \n", Fx) //The answer vary due to round off error
printf("Force exerted by Unit weight of water in direction perpendicular to direction of Jet, Fy=%.2f N/N of water \n", Fy)
