//Fluid Systems - By - Shiv Kumar
//Chapter 11- Centrifugal Pumps
//Example 11.5
//To Find the Discharge of Pump.
clc
clear
//Given Data:-
Hm=14.5; //Manometric Head, m
N=1000; //Speed, rpm
beta_o=30; //Vane Angle at outlet, degrees
Do=300; //Outer Diameter of the Impeller, mm
bo=50; //Width at Outlet, mm
eta_man=95/100; //Manometric Efficiency
//Data Used:-
g=9.81; //Acceleration due to gravity, m/s^2
//Computations:-
Do=Do/1000; //m
bo=bo/1000; //m
uo=%pi*Do*N/60; //m/s
Vwo=g*Hm/(uo*eta_man); //m/s
Vfo=tand(beta_o)*(uo-Vwo); //m/s
Q=%pi*Do*bo*Vfo*1000; //Discharge, litres/s
//Results:-
printf("The Discharge of the Pump=%.2f litres/s\n",Q) //The answer vary due to round off error
