Hose Flow Rate Formula
The following formula is used to calculate a hose flow rate.
Q = (1946.6 * D ^ 1.857 * (P/L) ) ^ .54
- Where Q is the volumetric flow rate in gallons per minute (GPM)
- D is the internal diameter of the hose
- P is the dynamic pressure of water
- L is the length of the hose
Hose Flow Rate Definition
A hose flow rate is defined as the total volume of water or fluid that moves through a hose per unit of time. This is most often measured in gallons per minute.
Hose Flow Rate Example
How to calculate a hose flow rate?
- First, determine the internal diameter.
Measure the inner diameter of the hose.
- Next, determine the length of the hose.
Measure the total length of the hose.
- Next, determine the dynamic pressure.
This is the dynamic pressure at the hose bib.
- Finally, calculate the hose flow rate.
Calculate the hose flow rate using the formula above.
