Question

If ρ is the density and η is coefficient of viscosity of fluid which flows with a speed v in the pipe of diameter d , the correct formula for Reynolds number R e is:

A

$R_e$ = $\frac{ηd }{ρν}$

B

$R_e$ = $\frac{ρν}{ηd}$

C

$R_e$ = $\frac{ρνd}{η}$

D

$R_e$ = $\frac{η}{ρνd}$

Answer

$R_e$ = $\frac{ρνd}{η}$

Explanation

Solution

The correct answer is (C) : $R_e$ = $\frac{ρνd}{η}$
$R_e$ = $\frac{ ρνd}{η }$
Direct formula based.
