Pipe Diameter Calculators

Easily determine the internal diameter of a circular pipe based on a given volume or mass flow rate and target flow velocity. Alternatively, verify the flow velocity for a known internal pipe diameter and specified flow rate. Designed for quick and straightforward calculations.

This tool allows you to quickly determine the internal diameter of a circular pipe based on a given volume or mass flow rate, target flow velocity, fluid density, and dynamic viscosity. Additionally, you can verify the flow velocity for a known internal pipe diameter and specified flow rate while considering fluid properties for more precise calculations.
