//Fluid system - By - Shiv Kumar
//Chapter 2 - Impact of Jet
//Example 2.8
clc
clear
//Given Data:-
d=75; //Diameter of the Jet, mm
V=14; //Velocity of the Jet, m/s
u=5; //Velocity of plate, m/s
//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
F=rho*a*(V-u)^2; //N
W=F*u; //J/s
KE=(1/2)*rho*a*V^3; //N-m/s
eta=W/KE*100; //In percentage
//Results:-
printf("(a)The Force exerted by the Jet on the plate, F=%.2f N \n", F) //The answer vary due to round off error
printf("(b)Work done by the Jet on the plate per second=%.1f N-m/s or J/s \n", W) //The answer vary due to round off error
printf("(c)Efficiency of Jet, eta=%.2f percent", eta) //The answer vary due to round off error
