Pipe Flow Rate and Velocity Calculator
Calculate volumetric flow from pipe internal diameter and mean velocity, or solve for velocity.
Pipe Flow Rate and Velocity Calculator User manual
- Fill in the parameters or select the file according to the form, and check the unit and format first.
- A 50 mm internal diameter and mean velocity of 1 m/s give approximately 7.06858 m³/h.
- Click the processing button to view the results, you can copy or download and save.
Calculation method and processing rules
Volumetric flow equals circular cross-sectional area multiplied by mean velocity. Results include L/s and m³/h.
scope of use
Assumes a full pipe and incompressible flow. Pressure loss and pump head are not calculated.
