Determine the volumetric and mass flow rate of a fluid with our flow rate calculator.

This flow rate calculator uses flow velocity and cross-sectional flow area data to determine the volumetric flow rate of liquid. You can calculate the flow rate in five simple steps:

Calculate water flow rates through pipes of various sizes and determine velocity, pressure requirements, and system performance. Available in both Imperial and metric units.

1) Water is flowing at 36 inches per second and at a rate of 1.0472 cubic feet per second. What is the pipe diameter? In this case we are solving for PIPE DIAMETER, so click on that button. …

Mar 24, 2025 · Getting the flow rate right helps your pump meet demand, keeps your system running smoothly, and can extend equipment life. In this guide, we’ll walk through how to …

With this tool, it is possible to easily calculate the average volumetric flow rate of fluids by changing each of the three variables: length, pressure and bore diameter.

Whether you’re analyzing a pipe pressure drop, calculating water velocity, or determining a fluid’s volumetric flow rate, the Pipe Flow Rate Calculator provides engineers, contractors, and …

In order to calculate the flow rate (F) the following equation is suitable: F = 1/4πP2V.

Calculate flow rate in pipes based on pipe diameter, pressure drop, and fluid properties using our Flow Rate Calculator.

Based on these inputs, the flow rate calculator will compute the volumetric flow rate (e.g., liters per second or cubic meters per hour) or the mass flow rate (e.g., kilograms per second).
