# C312 – Reynolds number calculation

## Description

This calculates Reynolds number based on options for flowrate/velocity and viscosity/density.

## Options

### Calculate from

- Mass flow rate
- Volume flow rate
- Flow velocity

Choose from available flow/velocity input.

### Viscosity

- Dynamic
- Kinematic

Choose from viscosity input.

## Calculation

The calculation uses one of the following flowrate/velocity, pipe dimension and viscosity relationships to calculate Reynolds number.

Where | ||
---|---|---|

Re | = | Reynolds number |

q_{m} | = | Mass flowrate |

q_{v} | = | Volume flowrate |

V | = | Velocity |

= | Density | |

= | Dynamic viscosity | |

= | Kinematic viscosity |
