The Reynolds number pVDmu is a very Important parameter In f

The Reynolds number, pVD/mu is a very Important parameter In fluid mechanics. Determine Its value for ethyl alcohol flowing at a velocity of 2 m/s through a 5-ln.-diameter pipe.

Solution

Assuming kinematic Visosity of ethyl alcohol at 20 C = 1.52 * 10^-6

Re = V * D / kinematic visocity

      = 2 * (5 * 0.0254) / 1.52 * 10^-6

      = 167105.26
