Answer:
The Reynolds number is defined as theproduct of density times velocity times length divided by the viscosity coefficient. ... The Reynolds number is used to study fluids as they flow. The Reynolds number determines whether a fluid flow is laminar or turbulent. Flowing fluids normally follow along streamlines.

Answer: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.
Formula : p.v.d (inertial force) / u (viscous force)
