How do I know the flow rate of my pool pump?

Divide the total gallons of water in the pool by the turnover rate in hours. Ideal turnover rate is between six and eight hours. To run the pump less time each day, lower the turnover rate. This will give you the gallons per hour or GPH.

How do I know what GPM my pool pump is?

And you just multiplied the pressure reading times 2.31.

What is the flow rate of a 1 HP pool pump?

You can see from the chart that a 1 horsepower pump will give you 52 gallons per minute on a system with 64 feet of head. We want to give you the flow information on each pump so that you can come up with the right pump the first time.

How many GPH is my pool pump?

To come up with this flow rate, simply divide your calculated gallons by eight. For the Rectangular pool example, the GPH required is 20,250 gallons / 8 hours or 2531 GPH. Most pool pump specifications are expressed in gallons per minute (GPM).

How do you check flow rate?

Begin your timer when you place the bucket under the flowing. Water. This will give you an open flow. Reading stop the timer when the bucket is filled or when it reaches your volume measurement.

How many gallons per minute does a 1.5 HP pool pump?

Pool Pump Operating Costs

Pump Size GPM (varies with plumbing) Cost/Hour
1.0 HP 60 $0.06
1.5 HP 68 $0.09
2.0 HP 76 $0.12
3.0 HP 85 $0.18

How many GPM will a 3/4 HP pump?

10 GPM

Horsepower: 3/4. Flow: 10 GPM @ 100′ with 50 PSI discharge pressure.

How do you calculate GPH water flow rate?

Write down this time. For example, consider your pump is able to fill the gallon container within 15 seconds. Divide the timed rate by 60 to find the gallon per minute rate: 60 divided by 15 equals 4. Multiply the gallon per minute rate by 60 to find the gph rate: 4 times 60 equals 240 gph.

How do you calculate flow rate through a filter?

Multiply the surface area of the filter by the velocity of the water through the filter to obtain the volumetric flow rate in gallons per minute. For example, for a surface area of 100 square feet and a velocity of 0.1 gallons per minute per square foot, (100 ft^2)*(0.1 gpm/ft^2) = 10 gallons per minute.
