You need to know the total pressure , what it use for, and the flow rate you want

The consultant requirement is booster pump , the capacity is 2L/S @ 3 Bar. Then he asked make the calculation te see if this pump is suitable for the system or not.

What shall I do?

that is the pump's spec?. you have to provide the total pressure lost of your system: the location with the highest press lost( vertical / horizontal piping , fittings, equipment( coil)). .

Thanks dear caibuadday

Could you please show me how to do the calculation for the pressure losses?
And if there is a programe doing so?

Thanks again.

Is it closed or open, what is t he height, what is it length(horizontal), what are the fittings in the horizontal section, pipe's size, the intended flow rate

ahmedsw · Jul 1, 2007, 03:10 AM

-it's closed
-it's pumped form high level to low level, i.g. from I.L. 6.00 to I.L -3.00
-the horizantal length is about 100 MTR.
-there is about 20 elbows , 5 TEES, and 8 valves.
The pipe's size are 65mm (10MTR),40MM (40MTR),32MM(25MTR),20MM(25).
Pump capacity is 2L/s @ 3 Bar.

How to calculate the pump head (static pressure of a four story building in which airconditioning plant installed at basement and ahu are each floor and bulding total height is 15metre

15 m is about 50ft, 50 x 0.433 = 21.7 or 22 psi; 36.7 psia or 2.5 atm... what is the height different between the pump and the heightest ahu; don't forget you still have lost through the chiller and ahu

Get

Get the pump curve from your supplier

Plot the system curve by getting several Head and Flow Rate points.
(Assume Q=0.5, 1.0, 1.5, get H=Static Head + Frictional Loss.)

If these two curves intersect at 3bar to 2L/s, then your selection correct.
