## Whst is reynold’s number, Physics

Assignment Help:

According to Reynolds, the critical velocity (vc) of a liquid flowing by a long narrow tube is

(a) Directly linked to the coefficient of viscosity of the liquid.

(b) Inversely linked to the density of the liquid and

(c) Inversely linked to the diameter

(D) of the tube. where R is the Reynold number.

If R occurs among 2000 and 3000, the flow is not stable and can change from streamline flow to turbulent flow.
