Question

Indicate the correct statement about the effect of the Reynolds number on the character of the flow over an object. If the Reynolds number is low enough, then the effect of viscosity is so:___.

a. high that there is a region near the plate where the fluid is stationary.
b. increases, then the size of the region around the object that is affected by viscosity increases.
c. is high enough, then the effect of viscosity is negligible and the fluid flows over the plate without sticking to the surface.
d. increases, then the extent of the region around the object that is affected by viscosity decreases.

Answer 1

Answer: d. increases, then the extent of the region around the object that is affected by viscosity decreases.

Step-by-step explanation:

Viscosity simply refers to the measure of the resistance of a fluid to a flow. The Reynolds number helps in the prediction of flow patterns.

If the Reynolds number increases, then the extent of the region around the object that is affected by viscosity decreases.
