can any one tell me proper method for head calculation for chilled water pump?

Question

if u have any project example thn plz send me on my mail.i know well all basic theory but i want see steps.hope u understand.i knw we will find pressure drop acorss fittings and in straight piping and across vlaves but i really need an example.of course chilled water sytem is a closed system.

hummmmm.i knw chilled water pump.i need methods to find head calculatuion to select chilled water pump set for a project.i have two chillers and i require abt 650 gpm for AHUS

try this website...might be helpfull...used it at work a few times.

Answer 2

Sunny, don't you have an engineer that can do this for you? You say you know all the basics, but then you still ask the question. Here's some of the stuff you have to know:
1. pressure drop through chiller
2. sizes and lengths of piping system
3. change in elevation from system's high point to pump suction
4. List of all fittings, valves, etc
5. Pressure drop through all your cooling units
6. required system pressure need to be maintained
7. required flowrate(s)
You just need to crunch the numbers to get your head calculations. You should have some reference material that will give you friction loss in pipes (usually per 100 foot of length) and tell you coefficients for calculating drops in fittings. Valve supplier should be able to tell you what the drop across the valves are.

Answer 3

Are you asking for the correct way for thinking about a chilled water pump?

Answer 4

NO no longer until God informed me to realize this yet no longer on your tintype. amused smiles. (((Sharon))) would you? i'm specific that's comparable to asking somebody what they'd do for a Klodike Bar? lol
