Question

The Reynolds number, rhoVD/μ is a very important parameter in fluid mechanics. Determine its value for ethyl alcohol flowing at a velocity of 5 m/s through a 1-in.-diameter pipe.

Answer 1

The Reynolds number for ethyl alcohol is 91,510

Step-by-step explanation:

Reynolds number (Re) = density×velocity×diameter/viscosity

density of ethyl alcohol = 789kg/m^3, velocity = 5m/s, diameter = 1 in = 0.0254m, viscosity of ethyl alcohol = 0.001095Pa.s

Re = 789×5×0.0254/0.001095 = 91,510
