Critical Velocity and Reynolds Number
Critical Velocity and Reynolds Number: Overview
This topic covers concepts, such as, Reynolds Number, Condition for Laminar Flow, Rate of Flow of a Fluid or Discharge 'Q', Inertial Force of Fluid in Motion, Critical Velocity, Significance of Reynolds Number & Unsteady Flow of Fluid etc.
Important Questions on Critical Velocity and Reynolds Number
The ratio of inertial force to viscous force represents:

Critical velocity is the velocity below which the flow of liquid is _____?

The critical velocity depends on the radius of the earth, mass of the earth and gravitational constant.

Define critical velocity?
