Reynolds Number Of Water Calculator

Hence the water flow is turbulent. It outputs the flow type you can expect laminar transitional or turbulent based on the reynolds number result.

With reynolds number calculator you can analyze what makes fluid flow regime laminar and what is needed to force the fluid to flow in the turbulent regime.

Reynolds number of water calculator. For reynolds number between 2100 and 4000 the fluid is in a transition zone between both types of flow it is not possible to confirm if it is laminar or turbulent. The reynolds number is a dimensionless value that measures the ratio of inertial forces to viscous forces and descibes the degree of laminar or turbulent flow. In our reynolds number calculator you can choose as a substance water at 10 cand you obtain reynolds number re 32 483.

The reynolds number for a pipe or duct expressed in imperial units. Re reynolds number non dimensional ρ density kg m 3 lb m ft 3 u velocity m s ft s μ dynamic viscosity ns m 2 lb m s ft l characteristic length m ft ν kinematic viscosity m 2 s ft 2 s. Here we can calculate for reynolds number density velocity characteristic length viscosity.

Knowing re one can anticipate the transition from laminar to turbulent flow which is the main utility of a reynolds number calculator. Below is a handy reynolds number calculator. Reynolds number is a dimensionless number that gives a measure of the ratio of inertial forces to viscous forces.

Systems that operate at the same reynolds number will have the same flow characteristics even if the fluid speed and characteristic lengths vary. Calculator this calculator computes the reynolds number given the flow characteristics asked for below. The reynolds number is calculated from.

The reynolds number re is a dimensionless quantity for dynamic similarity and is calculated as the ratio of inertial forces to viscous forces of a flow of liquid. For example in pipes with minimal internal diameter it is more likely to have laminar flow regime with small reynolds number even for a fluid with low viscosity. It happens for reynolds numbers above 4000.
