Reynolds Number given Length Solution

STEP 0: Pre-Calculation Summary

Formula Used

Reynolds Number = Density of Liquid*Velocity*Length/Kinematic Viscosity
Re = ρ₁*v_f*L/V_k
This formula uses 5 Variables

Variables Used

Reynolds Number - The Reynolds Number is the ratio of inertial forces to viscous forces within a fluid which is subjected to relative internal movement due to different fluid velocities.
Density of Liquid - (Measured in Kilogram per Cubic Meter) - Density of Liquid is mass of a unit volume of a material substance.
Velocity - (Measured in Meter per Second) - Velocity is a vector quantity (it has both magnitude and direction) and is the rate of change of the position of an object with respect to time.
Length - (Measured in Meter) - Length is the measurement or extent of something from end to end.
Kinematic Viscosity - (Measured in Square Meter per Second) - The kinematic Viscosity is an atmospheric variable defined as the ratio between the dynamic viscosity μ and the density ρ of the fluid.

What is Reynolds number and what is its importance?

The Reynolds number, referred to as Re, is used to determine whether the fluid flow is laminar or turbulent. It is one of the main controlling parameters in all viscous flows where a numerical model is selected according to pre-calculated Reynolds number

How does Reynolds number effect flow?

The Reynolds number (Re) helps predict flow patterns in different fluid flow situations. At low Reynolds numbers, flows tend to be dominated by laminar (sheet-like) flow, while at high Reynolds numbers flows tend to be turbulent. ... Reynolds numbers are an important dimensionless quantity in fluid mechanics.
