//Fluid system - By - Shiv Kumar
//Chapter 2 - Impact of Jet
//Example 2.9
clc
clear
//Given Data:-
d=65; //Diameter of the Jet, mm
V=20; //Velocity of the Jet, m/s
u=8; //Velocity of curved vane, m/s
AoD=160; //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
theta=180-AoD; //degrees
Fx=rho*a*(V-u)^2*(1+cosd(theta)); //N
P=Fx*u/1000; //Power of Jet, KW
KE=(1/2)*rho*a*V^3; //Kinetic energy of Jet per second, N-m/s(W)
eta=P*1000/KE*100; //In percentage
//Results:-
printf("(a)The Force exerted on plate in direction of Jet, Fx=%.2f N \n", Fx) //The answer vary due to round off error
printf("(b)Power of Jet=%.3f KW \n", P) //The answer vary due to round off error
printf("(c)Efficiency of Jet, eta=%.2f percent", eta)
