//Fluid Systyems - By Shiv Kumar
//Chapter 16- Hydraulic Power and Its Transmission
//Example 16.18
//To Find (i)The Load Lifted by Crane (ii)The Quantity of Water needed to Lift the Load.
clc
clear
//Given Data:-
d=200; //Diameter of Ram, mm
p=7.5; //Pressure of Water Supplied, MPa
VR=6; //Velocity Ratio
eta=50/100; //Efficiency of Crane
h=10; //Height through which water is to be lifted, m]
//Computations:-
d=d/1000; //m
p=p*10^6; //Pa
Fp=(%pi/4)*d^2*p; //Pressure Force Exerted on Ram, N (answer vary due to value of %pi)
W=Fp*eta/VR; //Load Lifted by Crane, N
Vw=(%pi/4)*d^2*h/VR*1000; //Quantity of Water needed, Litres
//Results:-
printf(" (i)The Load Lifted by Crane, W=%.f N \n",W) //The answer provided in textbook is wrong
printf(" (ii)The Quantity of Water needed to Lift the Load by 10 m =%.2f Litres \n",Vw) //The answer vary due to round off error
