This tool calculates the friction factor for fluid flow in pipes quickly and accurately.

## How to Use the Friction Factor Calculator

This calculator helps determine the friction factor for fluid flow in a pipe, using the Darcy-Weisbach equation. Fill in the pipe diameter (in meters), pipe roughness (in meters), flow velocity (in meters per second), and kinematic viscosity (in square meters per second). After filling in these values, click ‘Calculate’ to get the friction factor.

## How It Works

The friction factor is calculated based on the Reynolds number. If the Reynolds number is less than 2300, the flow is considered laminar, and the friction factor is calculated using the formula: `f = 64 / Re`

, where `Re`

is the Reynolds number. For turbulent flow (Reynolds number greater than 2300), an iterative approach based on the Colebrook-White equation is used.

## Limitations

This calculator assumes steady state flow and circular pipe cross-section. It does not account for factors such as changes in flow direction, pipe fittings, or temperature variations. The accuracy of the results is dependent on the precision of the input values you provide.
