Question

The Reynold's number for a liquid flow in a tube does NOT depend on ______.

Options

• the velocity of the liquid

• the viscosity of the liquid

• the length of the tube

• the diameter of the tube

Answer 1

The Reynold's number for a liquid flow in a tube does NOT depend on the length of the tube.

Explanation:

Reynolds number R_n = `("V"_"c"rho"d")/"n"`

where V_c = Critical Velocity, ρ = density

η = coefficient of viscosity, d = iameter of the tube

It is independent of the length of the tube.
