The flow rate of water in gallons per minute, or gpm, can be calculated with the help of the Bernoulli equation and careful unit conversion. If the pressure is known in pounds per square inch, or psi, at two locations along the pipe, then the Bernoulli equation can be used to determine...
So what is GPM, and how do you calculate it? Browse Our Pumps What Is GPM? GPM stands for gallons per minute and is a measurement of how many gallons a pump can move per minute. It is also referred to as flow rate. GPM is variable based on another measurement known as the Head,...
Hydraulic dump trucks use hydraulic hoist systems to lift the bed of the dump truck when it needs to be emptied. Princeton University defines "hydraulic" to mean something that is moved or operated or effected by liquid, such as water or oil. Parts ••• Dump truck hydraulic systems a...
With this knowledge, we can quickly identify that a valve with a Cv of 10 will flow 10 GPM of water at 1 psi pressure drop across the valve without any math. A practical example, if we wanted to calculate Cv to select a valve for 10 GPM flow with a required ΔP of 4, first find...
Three tables to get a general understanding of water flow capacity through a pipe or roof drain. If you have questions, contact our roof Drain Wizard.
And even for modest water entry, the projection of that sump bucket lip above the floor level means water has to rise a few inches in this basement before it can even flow into the sump pit! In a good situation, openings in the sides and bottom of the sump pit (photo at left) ,...
The flow of your H2O could become weak for a number of reasons. Here’s what you should do to improve your home's water pressure.

Use the same basic calculation to solve for water height instead. For example, you can determine the depth of water from a pressure gauge reading. In the example above, having an accurate pressure gauge in the tank's down pipe at ground level would allow you to calculate the water's heigh...
Rate of Flow Therate of flow (Q)is the variable that represents how much of the fluid is passing through the valve at a given time. We usually represent this number in GPM (Gallons Per Minute). To calculate the rate of flow, you need to know the volume (V) and the time (t) it...
