Reynold's Number

Question 1

What is Reynold’s Number

Answer 1

Reynolds number is a dimensionless quantity that is used to determine the type of flow pattern in a fluid, whether it is laminar or turbulent

Question 2

Reynold’s Number Formula

Answer 2

R = pVD
———
u

R -> Reynold’s Number
p -> Density of Fluid
V -> Velocity of Flow
D -> Pipe Diameter
u -> Viscosity of Fluid

Question 3

When is flow turbulent or laminar (using Reynold’s Number)

Answer 3

If R > 2000 -> Turbulent Flow
If R < 2000 -> Laminar Flow
