If

\rho

is the density and

\eta

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:

View answer and explanation

Correct option: C

{R_e} = \frac{{\rho vd}}{\eta }

Option C (

{R_e} = \frac{{\rho vd}}{\eta }

) is correct because it is the standard formula for calculating Reynolds number.

poise. A liquid rises to a height of 2 cm in a capillary tube. The angle of contact between the solid and the liquid is zero. The tube is depressed more so that the top of capillary tube is only one cm above the liquid. Then the apparent angle of contact between the solid and liquid is An object weights
