The nature of flow of a fluid inside a tube i.e., whether it is turbulent or laminar, is ascertained by
A)Viscosity of fluid
B)Flow velocity
C)Surface conditions
D)Tube size
E)Reynolds number

Question

Quizplus · Accepted Answer

The Reynolds number is a dimensionless quantity used in fluid mechanics to predict flow patterns in different fluid flow situations. It is calculated using properties such as viscosity of fluid, flow velocity, and characteristic dimensions (e.g., tube size), and it incorporates the effects of surface conditions indirectly. Therefore, it is the key parameter that ascertains whether the flow of a fluid inside a tube is turbulent or laminar, encompassing the effects of all the other options listed.
