Sample flow test results.
Water flow test calculator.
I n s t r u c t i o n s.
Making this calculator quite versatile.
This application has auto adjusting axis divisions and automatically calculates avaliable flow or pressure at a single point.
Projected available hydrant flow.
Input and output support metric and imperial.
Unlike other calculators you are not confined to inputting diameter in inches velocity in miles per hour etc.
The rated capacity calculation is useful in determining the total water supply at a given point in the hydrant or water main.
A fire hydrant flow test is a process of flowing water out of at least one fire hydrant while obtaining the required pressures static residual and pitot needed to calculate the amount of water in gallons per minute gpm that the water system is capable of providing between the tested hydrants.
This calculator may also be used to determine the appropriate pipe diameter required to achieve a desired velocity and flow rate.
The main can be expected to flow about.
This ultra calculator is special by allowing you to choose among a great variety of units 6 for diameter and 24 each for velocity and flow rate.
Nfpa and awwa predicted flow of any fire hydrant is based on the rated capacity at 20 psi.
Residual pressure is measured from the same cap gauge while water is flowing.
The flow rate calculator can also calculate the mass flow rate of liquids given the liquid density is known.
Gallons per minute is measured by a diffuser with a pitot and a gpm gauge while the hydrant is flowing.
Easily calculate the volumetric flow rate of a pipe a k a.
The hydrant flow test calculator measures the rated capacity at 20 psi of a fire hydrant.
Secondary psi before flowing.
All hydrants are assumed to provide at least 20 psi.
Discharge rate given its diameter for a round pipe height width for a rectangular one and the velocity of the liquid or gas flowing through it.
Our interactive flow calculator will do the hard work of working out if you have issues with your water.
Gpm from the test outlet.
The following formula is used by this calculator to populate.
Quickly determine you water supply capabilities with our on line application for graphing fire hydrant flow test information on a logritmic graph n 1 85.
With this diameter velocity and flow rate calculator you can determine the exact flow rate or velocity at which water will flow through any given pipe.
American water works association awwa 2 defines the required fire flow as the rate of water flow at a residual pressure of 20 psi and for a specified duration that is necessary to control a major fire in a specific structure each fire flow methodology may define the objective of the required fire flow differently.
Secondary psi while flowing.
