# Reynolds Number Equations Calculator

Engineering Fluid Mechanics Design Formulas
Reynolds Number assists in the analysis of the type of fluid flow: laminar, turbulent and transitional. It describes the relationship between viscous force and inertial force.

Solving For Characteristic Length.

## Inputs:

Reynolds Number (Re)
unitless
viscosity (μ)
density(ρ)
velocity (V)

## Conversions:

Reynolds Number (Re)
= 0
= 0
viscosity (μ)
= 0
= 0
N-s/m^2
density(ρ)
= 0
= 0
kilogram/meter^3
velocity (V)
= 0
= 0
meter/second

## Solution:

characteristic length (l)
= NOT CALCULATED
