Reynolds Number Calculator

This Re calculator is used to find the reynolds number and it is help predict flow patterns in different fluid flow situations.


Newtonian Fluid Reynolds Number Formula:

Reynolds number(Re) is a dimensionless value which is applied in fluid mechanics to represent whether the fluid flow in a duct or pat a body is steady or turbulent.

Re = ρ V Dμ


Re - newtonian fluid reynolds number

μ - fluid dynamic viscosity in kg/(m.s)

ρ - fluid density in kg/m3

V - fluid velocity in m/s

D - pipe diameter in m

Note: If value of Reynolds number is less than 2000, then the flow of liquid is laminar.
