Pitot Gauges: How Do I Calculate the PSI to GPM Conversion?

The captured PSI readings from a group of hydrants in the same vicinity are then used to calculate the disparities in pressure between two points along the distribution system. But in order to understand the results, the PSI readings need to be converted to GPM, the standard measurement of water flow.

Relationship of Flowrate and Pressure for Positive ...

the flow rate is reduced by 40% (to about 30 GPM). Referring to the positive displacement pump curve, when operated at approximately 740 RPM the flow rate will be approximately 50 GPM at 200 PSI and about 48.6 GPM at 700 PSI; a decrease in flow of about 3% based upon a 350% increase in pressure. Therefore, centrifugal pumps have a flow rate

Pressure Washer PSI | Pressure Washer Specs | PSI and GPM

The relationship between PSI and GPM is demonstrated through a measurement called Cleaning Units, or CU. This number is found by multiplying the PSI and GPM. A washer with 3000 PSI and a 3 GPM will have a CU of 9,000. A washer with 3,500 PSI and a 2 GPM will only have a CU of 7,000. So the pressure washer with the lower PSI will actually get ...

Understanding Pressure Washers PSI and GPM Rating

A 2,000 PSI rated machine that runs at 4 GPM will produce a CU of 8,000 (PSI X GPM = CU). Similarly, a 2,500 PSI rated machine that runs at 2 GPM will result in a CU of only 5,000. In this case, because it has a higher CU rating, the lower PSI machine will get …

Mar 11, 2011· HP = ( 50 gpm x 50 psi ) / ( 1714 x 0.75 efficiency ) = 1.95 HP. Suppose you succumb to the hype and shuck out some really big bucks for an allegedly 90% efficient pump. That pump (at the same flow and pressure) will consume: HP = ( 50 gpm x 50 psi ) / ( 1714 x 0.90 efficiency ) = 1.62 HP. WOW. A net gain of a full 1/3 of a HP.

GPM to RPM Conversion | It Still Runs

The most accurate way to convert GPM to RPM is to do a test. Run the pump at 1,000 RPM, for example. Once 1,000 RPM is reached, direct the fluid being pumped into a measuring container for one minute. This will give you the accurate GPM measure of your pump at 1,000 RPM. With this measure, you can estimate the RPM of the pump if you know the ...
