How long to run pump & at what speed?

[ePoolUser]

Could someone put this formula into layman's terms? I don't see where head loss fits into the formula..
>>First you need to determine head loss. In most pools that is between 45-65 ft on high speed ...
Then determine your turnover rate. Turnover (hours) = Pool Volume / GPM / 60<<

Where is head loss used in the equation?

Obviously I'm missing something (brains?).

TIA,
Steve

Here is what I had posted regarding converting head loss to GPM:

Next look up the flow (GPM) on the pump head curve for both high and low speeds. Low speed should be 1/2 of high speed GPM. Low speed head loss should be 1/4 of high speed.

Usually, the pump head curve is in your pump manual. The vertical axis is head loss and the horizontal is GPM.
