Water Flow Test Calculator

Residual pressure is measured from the same cap gauge while water is flowing.

Water flow test calculator. Unlike other calculators you are not confined to inputting diameter in inches velocity in miles per hour etc. Gallons per minute is measured by a diffuser with a pitot and a gpm gauge while the hydrant is flowing. 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. All hydrants are assumed to provide at least 20 psi.

Secondary psi before flowing. Gpm from the test outlet. Our interactive flow calculator will do the hard work of working out if you have issues with your water. Secondary psi while flowing.

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. All you need for the test is a measuring jug and a timer. Projected available hydrant flow. Input and output support metric and imperial.

The calculation offers more useful information than the test flow by itself and is used by insurance underwriters. Sample flow test results. 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. The main can be expected to flow about.

Easily calculate the volumetric flow rate of a pipe a k a. 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. The flow rate calculator can also calculate the mass flow rate of liquids given the liquid density is known. This application has auto adjusting axis divisions and automatically calculates avaliable flow or pressure at a single point.

I n s t r u c t i o n s. The rated capacity calculation is useful in determining the total water supply at a given point in the hydrant or water main. 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. Take the test now.

The hydrant flow test calculator measures the rated capacity at 20 psi of a fire hydrant. Making this calculator quite versatile. The following formula is used by this calculator to populate.
