Water Flow Calculator

We regularly get asked about the water flow capacity of different pipe sizes and which is the best roof drain for a specific pipe size.

Water flow calculator. In our example water has a flow rate of approximate 998 kg m the density of water at 68 f 20 c. Making this calculator quite versatile. This calculator may also be used to determine the appropriate pipe diameter required to achieve a desired velocity and flow rate. The flow rate calculator can also calculate the mass flow rate of liquids given the liquid density is known.

Garden hose flow rate and timewashington state university this tool provides the flow rate through a garden hose based on the inputs of hose size hose length and supply pressure. The tool displayed a mass flow rateof 30 58 lbs s. Flow rate calculator easily calculate the volumetric flow rate of a pipe a k a. Select the shape of the cross section of the channel input all the measurements required to compute the cross sectional area.

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. That said we put together the following tables to serve as general guides for estimating a pipe s water flow capacity. Includes 53 different calculations. You only need to know the diameter of the pipe the material it s made of its length and the drop in height.

Use this pipe flow calculator to analyse the properties of water flowing in a gravity fed system. What is the pipe diameter. The most important step in using this calculator is. 1 water is flowing at 36 inches per second and at a rate of 1 0472 cubic feet per second.

Unlike other calculators you are not confined to inputting diameter in inches velocity in miles per hour etc. Unfortunately recommendations aren t that straightforward because you also need to account for water pressure material friction and more. 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. Length pressure and bore diameter.

However if you want to be super accurate check out our water density calculator as the density changes with temperature salinity and pressure. We then apply the hazen williams equationfor you which calculates the resulting velocity and discharge. Online calculator to quickly determine water flow rate through piping. Copely tools flow rate calculator with this tool it is possible to easily calculate the average volumetric flow rate of fluids by changing each of the three variables.
