Explain Reynolds Number.

Text Solution

Verified by Experts

Reynolds number is a dimensionless number It depend on density of fluid `(rho)`,velocity of fluid , diameter of tube (D) and coefficient of viscosity `(eta)`.
`N_(R)=(rhovD)/(eta)` From Reynolds number types of flow of liquid can be determined.
