Answer:
Flow of fluid in a conduit:
During, the flow of fluid inside the conduit or pipe occurs in different patterns due to the inconsistency found inside the velocity of the fluids. Which some times make it laminar while other times the flow of fluids is non-streamline in nature.
Explanation:
Critical velocity:
During, the flow of fluids inside the passage or conduit the water flow has different values for velocity at each point, because at first the flow is very streamlined or well organized in a given pattern, but when the interact between the wall of the conduit or the pipe and the fluid occurs, we see a more diffused form of flow inside the flow of the fluid. And at which such velocity occurs is called as the critical velocity.
