| Pump and Filter Sizing

Yes... the modern pool environment can often
look like a plumbers' nightmare.

| The need for proper flow rates is essential, no matter
the complexity of the design. If a solar system is added to the pool proper sizing of the
pump and filter also becomes important in the overall performance of the solar system. |
 |
|
 |
The real trick is to balance
the flow rates and head requirements of all the equipment so as not to adversely affect
any portion of the pool. Pool sweeps, especially high pressure pop-up head systems require
special attention and sometimes require booster pumps for solar loops or larger filter
designs. |
|
| Chlorine generators, gas heaters, heat pumps,
solar systems all require certain gallon per minute rates and each have different levels
of restriction or head loss for those flow rates. When designing a complex pool project it
is advisable to have manufacturers' flow and pressure drop tables to insure balanced flow
for elements of the pool. |
|
The
total pool capacity is determined by first arriving at the surface area of
the pool. As most heat loss is at the surface, this is a figure to be saved for later use.
Second, determine the average depth, and finally multiply by 7.5 gallons per cubic feet to
attive at the total gallons. |

Cubic Feet x 7.5 gallons/per

Example...A=14' and B=16' with L=32'
A) 14' + 16=30' divided by 2 =15' ..average width.
B) 15' x 32' =
480 sq.ft. Usually a factor of
.90 is used to account for the freeform
nature of this pool or a total of 480 x .90= 432sq.ft.
To gain a more accurate average width and skip
using the modifier of .90 simply take 4 or 5 width
measurements and average them by adding all
together and dividing by the number of
measurements taken. For a round pool
use.....
Area = R x R x 3.14 then (pool area) x (average depth) x 7.5 = gallons
