//Fluid system - By - Shiv Kumar
//Chapter 2 - Impact of Jet
//Example 2.27

//Given Data:-
H=3.8; //Head of water in tank, m
d=200; //Diameter of orfice, mm
Cv=0.97;
u=2; //Velocity of tank, m/s
//Data Used:-
rho=1000; //Density of water, kg/m^3
g=9.81; //Acceleration due to gravity, m/s^2
//Computations:-
d=d/1000; //m
a=(%pi/4)*d^2; //cross-sectional are of orifice, m^2
V=Cv*sqrt(2*g*H); //Velocity of Jet, m/s
//(a)
F=rho*a*(V+u)*V; //N
//(b)
W=F*u; //N-m/s
//(c)
eta=2*V*u/(V+u)^2*100; //in Percentage
//Results:-
printf("(a)Propelling Force on tank, F=%.2f N \n", F) //The answer provided in the textbook is wrong
printf("(b)Work done by propelling force per second=%.2f N-m/s \n", W) //The answer provided in the textbook is wrong
printf("(c)Efficiency of propulsion, eta=%.2f percent", eta) //The answer vary due to round off error
