Reynolds Number Calculator

This calculator calculates the Reynolds Number using the flow characteristics provided. 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.
