Quite often the gpm is marked on the aereator on the outlet of the faucet. Otherwise, time how long it takes to fill a gallon jug. A 1gpm faucet will take one minute to fill a gallon jug.
There are 12,000 Btus per ton of cooling. In order to determine tons of cooling, the formula is: Tons = (dT x GPM) / 24 If you would like to know the tons of cooling in Btus, you would multiply this formula by 12,000.. Tons (Btu) = (dT x GPM x 12,000) / 24 Basic arithmetic yields: Tons (Btu) = (dT x GPM x 500) {12,000 / 24 = 500}

It depends on flow. 2 PSI for 500 GPM 8 PSI for 1000 GPM 18 PSI for 1500 GPM 32 PSI for 2000 GPM This is per 100' ft If your flows are big, ie. defensive conditions, you must relay for anything over a couple hundred feet in length. Capt. Ridgeway Tumwater Fire
45 gph x 60 min/1 hr so multiply by 60 45 gph is 2700 gpm
A fixture unit is 1 cubic foot of water (7.48 gallons) If your using pumped drainage /soil system then for every GPM of flow rate one has to consider it as ONE FU
what is the GPM rating from the old to the new the lower the GPM the slower the water. Sometimes there are restrictor discs (washers).
Most domestic ones flow at a little over 2 gpm.

The average kitchen faucet in a house will supply 2.5 -3 gallons per minute at 50 PSI. That is an average hose working pressure in north America. A large bath faucet will supply 3 + gpm and a single lever bathroom sink faucet will be about 2 gpm.
The GPM rating on a pressure washer refers to the gallons of water it can spray per minute. This rating indicates the machine's water flow capacity, which is important for determining its cleaning power and efficiency.
The optimal flow rate for a bathroom faucet is typically around 1.5 to 2.2 gallons per minute (GPM) to balance water conservation and efficient use.
The ideal GPM rating for a pressure washer to ensure optimal cleaning performance is typically between 2.3 to 2.5 gallons per minute.
The ideal GPM rating for a pressure washer to effectively clean outdoor surfaces is typically between 2.3 to 3.5 gallons per minute.
0.4 GPM stands for 0.4 gallons per minute, which is a measurement of flow rate. It indicates the amount of liquid, typically water, that flows through a system, such as a faucet or pump, in one minute. This value is often used to assess the efficiency of appliances or plumbing systems. A lower GPM may suggest slower flow, while a higher GPM indicates a faster rate of delivery.
The average kitchen faucet will deliver about 2.5 gpm. Some will be more and some less.

. -Most pumps actually have a GPM rating on spec. plate.
