Question

For fluids, the velocity of fluid elements at the surface of stationary solids is taken to be zero. This rule is often referred to as the:

A. continuum hypothesis
B. Newton's law of viscosity
C. No-slip condition
D. Momentum flux

Answer 1

The rule that states the velocity of fluid elements at the surface of stationary solids is taken to be zero is called the No-slip condition.

Step-by-step explanation:

The rule that states the velocity of fluid elements at the surface of stationary solids is taken to be zero is called the No-slip condition. This condition assumes that when a fluid comes into contact with a solid surface, it sticks to the surface and does not slip past it. This phenomenon can be observed, for example, when water flows from a hose into a narrow spray nozzle: It emerges with a large speed, and this is possible because of the no-slip condition.
