Question

what is reynolds number?

Answer 1

reynolds number--it is a ratio to inertial forces to viscous forces and consequently quantities that are relative importance of these forces....

that's Riya ✌✌✌....

Answer 2

The Reynolds number is defined as the product of density times velocity times length divided by the viscosity coefficient. This is proportional to the ratio of inertial forces and viscous forces (forces resistant to change and heavy and gluey forces) in a fluid flow.
