How to determine appropriate wter pump

[jmikl]

A constant volume of 1800 cf of water needs to be introduced into the base of a 60 ft tall (15x15) water tank. I need to determine the hp/kw needed in order to do this. Can anyone explain the math on determining this?

Thx

If the volume of water is constant, whats the pump for?

[jmikl]

continuous flow, costant flow.

[Strugglin Man]

You need the flow in, say, gallons per minute, cf per hour, or lbs per hour,,,,,,,,

amount of water / amount of time

after that it's straightforward.

Good Luck

[jmikl]

cubic feet per minute flow

Thx

Static pressure times flow rate = power. Divide by pump efficiency to get motor power.

Static pressure times flow rate = power. Divide by pump efficiency to get motor power.

Thx Russ. I am still not sure how to calculate it.

25.92 (water pressure at 80 ft) xxxx gpm ?

jm,

Hydrualic HP = lbs of liquid per minute x head (in feet) / 33,000

Pump HP = Hyd HP/Pump Efficiency

After you work this out, call your trusted pump vendor/mnfr, and work out w them the most logical pump to purchase based on your specific needs/ conditions.
