Gallon per minute is a volume flow rate unit and is the most common way to measure water. It’s used in many different applications, including determining how long it will take to fill a container and evaluating the performance of a pump or other appliance.
GPM can also be referred to as gallons per hour (GPH) or cubic feet per minute. The number of gallons that can be drawn down in one minute depends on the type and pressure of the hose or tank. In general, garden hoses will have a water flow rate of 9 to 17 GPM, while high-pressure systems may produce more than that.
The simplest way to calculate GPM is to use a container of known capacity and time how long it takes for it to be filled. This can be done by setting a stopwatch or using the built-in clock on your smartphone. Then, divide the total volume of the container by the amount of time that passed and multiply by 60.
To calculate GPM from PSI, you can use the same method as above. However, it is important to remember that GPM measures the flow rate of liquid, while PSI is a unit of pressure. To get the tank pressure, you must subtract atmospheric pressure from the reading on the pressure gauge, then divide the result by the density of water and multiply by 2. You will get the tank pressure in PSI. gpm to lpm
