Reynolds Number Calculator

Reynolds wide variety:

The Reynolds number is the dimensionless fee and the ratio among the inertia and viscosity of the liquid. It describes the diploma of the laminar and turbulent flow fee. The Reynolds variety stays consistent and has the equal traits if the liquid speed and length vary.

The Reynolds wide variety formula:

The Reynolds quantity calculation is the same for all the beverages, you want to go into the specific parameter for each liquid. you could calculate Reynolds wide variety by way of the following method:

Re = [(ρ * u * L) / μ]

Now, The Kinematics viscosity of a liquid ν = μ / ρ Re = [( u * L) /ν]

Where:

• Re is the Reynolds quantity
• ρ is the density of liquid(check the density of air at a given temperature via air density calculator)
• u is the rate of the item with appreciate to the object
• L is the traits Linear dimension of liquid.
• μ is the dynamics of the viscosity of the fluid
• v is the Kinematic Viscosity of a fluid (ν = μ / ρ)

Reynolds quantity example:

find the Reynolds number water and consider the water float size as L = 2.5 cm Pipe. the velocity of the faucet water is round u = 1.7 m/s and the temperature is 10 °C.

Given: 

Water waft dimension L = 2.five cm

traits Linear measurement u = 1.7 m/s

Temperature T= 10 °C

Solution:

The water viscosity at 10 °C = 999.7 kg/m3 (regular)

Dynamics Viscosity μ = 0.001308 Kg/m-s

Kinematics viscosity ν = μ/ρ = 0.0000013084

The Reynolds number system is:

Re = [(ρ * u * L) / μ]

or                                      

Re = [( u * L) /ν]

Water Reynolds variety = 32483
