//Fluid Systems - By Shiv Kumar
//Chapter 16- Hydraulic Power and Its Transmissions
//Example 16.2
//To Determine the Flow Rate and the Minimum Diameter of Pipe.
clc
clear
//Given Data:-
P=1000; //Power Transmitted, kW
eta=85/100; //Efficiency
l=500; //Length of the Pipe, m
H=150; //Head of Water at Inlet, m
f=0.006;
//Data Required:-
rho=1000; //Density of Water, Kg/m^3
g=9.81; //Acceleration due to gravity, m/s^2
//Computations:-
hf=H*(1-eta); //m
Q=P*10^3/(rho*g*(H-hf)); //m^3/s
d=(64*f*l*Q^2/(2*g*%pi^2*hf))^(1/5); //m
//Results:-
printf("The Required Flow Rate, Q=%.4f m^3/s\n",Q)
printf("The Minimum Diameter, d=%.4f m\n",d) //The answer vary due to round off error
