This calculator calculates the Reynolds Number using the provided flow characteristics. Depending on the flow regime, the calculator informs whether it is one or another.
This number tells us what type of flow is expected for a given pipe, whether laminar, transitional or turbulent.
By convention, there is an approximate number of Reynolds where the limits of some regimes are defined. In systems whose Re is less than 2000 there is no turbulence. This non-turbulent regime is called laminar flow. Systems whose Re is greater than 2000 are turbulent.
To use the calculator, you can access Reynolds Calculator.
For now, I have implemented the conversion of some units of measurement. They are:
- Free-stream fluid velocity, V
- m/s
- cm/s
- mph
- km/h
- ft/s
- in/s
- km/s
- Characteristic distance (or pipe diameter), L
- m
- cm
- mm
- µm
- nm
- ft
- in
- Fluid density, ρ
- kg/m³
- kg/l
- g/mm³
- lb/in³
- Fluid viscosity (dynamic), η
- Pa⋅s
- mPa⋅s
- cP
- kg/m⋅s
- slug/ft⋅s
