//Fluid Systems - By Shiv Kumar
//Chapter 12- Reciprocating Pumps
//Example 12.4
//To Find whether seperation will take place, and if so, at which section of pipe.

//Given Data:-
ld=60.96; //Length of Delivery Pipe, m
a=1.83; //Acceleration of Plunger Pump, m/s^2
A_by_ad=2; //ratio of Sectional Area of Plunger to that of Delivery Pipe.
//Referring to Fig 12.6 in the textbook,
ef=18.3; //m
eq=12.19; //m
dq=1.83; //m
slope=3;
Hsp=2.44; //Pressure Head in pipe when seperation takes place, m of water
Hatm=10.36; //Atmospheric Pressure Head (Barometer Reading), m of water
//Data Used:-
g=9.81; //Acceleration due to gravity, m/s^2
//Computations:-
Had=-(ld/g)*A_by_ad*a; //Head at end of stroke, a=acceleration=omega^2*r, Had in m
dp=Had; // Referring to Fig 12.6 in the textbook
ed=eq+dq;
Hd=ed; //Total Delivery Head, m
Hrd=Had+Hd; //Resultant Pressure in Delivery pipe at end of Stroke, m
Habs=Hatm+Hrd; //Absolute Pressure. m of water
Hv=Hatm-Hsp; //Vaccum pressure, m
x=-Hv-Had; //m
if Habs<Hsp then
printf("The Seperation Will Take Place at x=%.2f m\n",x) //The answer vary due to round off error
else
