calculating horsepower consumed across parallel pipe
calculating horsepower consumed across parallel pipe
(OP)
I can't remember...
...For purposes of calculating horsepower consumed across parallel pipe paths, when flow is equally distributed across parallel paths of the same size, are the pressure drops across the individual runs additive
I mean...do you find HP based on...
HP = [Qtotal * (SUM Hindividual)] / 3956...
or
HP = SUM (Qpartial * Hindividual) / 3956...?

Or sum up the flow times pressure drop times constant for each parallel leg.
OH, assuming a liquid.

So for - say - I don't know...15 psig across each of three paths with 10 GPM dividing equally - 3.33 GPM per path - then it's 10 GPM x 15 psig - just one of the delat-P values?
PS: can you elaborate on the "constant" you mention?

Total power = HPb1 + HPb2 + ... + HPbn
