Water Flow Calculator Online

Use this pipe flow calculator to analyse the properties of water flowing in a gravity fed system.

Water flow calculator online. 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. This flow rate calculator uses flow velocity and cross sectional flow area data to determine the volumetric flow rate of liquid. Click the calculate button and the answer is 5 236 cubic feet per second and the answer is in 23 other different units. First click on what you are solving for flow rate.

The tool displayed a mass flow rateof 30 58 lbs s. Online calculator to quickly determine water flow rate through an orifice. You only need to know the diameter of the pipe the material it s made of its length and the drop in height. We then apply the hazen williams equationfor you which calculates the resulting velocity and discharge.

Enter 2 in the pipe diameter box and choose feet from its menu. In our example water has a flow rate of approximate 998 kg m the density of water at 68 f 20 c. However if you want to be super accurate check out our water density calculator as the density changes with temperature salinity and pressure. Click on the calculate button to compute the flow rate.

Input all the measurements required to compute the cross sectional area. Equations displayed for easy reference. This calculator may also be used to determine the appropriate pipe diameter required to achieve a desired velocity and flow rate.
