Calculate the Reynolds number to determine whether fluid flow is laminar or turbulent. This dimensionless number is critical for predicting flow behavior in pipes and around objects.
Enter your values below
Density of the fluid
Fluid velocity
Pipe diameter or characteristic length
Dynamic viscosity of the fluid
How this calculator works
The Reynolds number equals fluid density times velocity times characteristic length divided by dynamic viscosity.
