Vertical profiles of longshore currents and related bed ...

Turbulence induced by breaking waves modifies the vertical profile of longshore currents. The downward momentum mix- ing produced from wave breaking-injected turbulence results in a more uniform velocity profile. Fredsoe and Deigaard [1992] and Church and Thornton [1993] argue that this would result in an increased bed shear stress.

Fluid Flow Velocity Profiles - Engineers Edge

Fluid Flow Velocity Profiles. Not all fluid particles travel at the same velocity within a pipe. The shape of the velocity curve (the velocity profile across any given section of the pipe) depends upon whether the flow islaminar or turbulent. If the flow in a pipe is laminar, the velocity distribution at a cross sectionwill be parabolic in ...

Fluid velocity in a vertical pipe - Physics Stack Exchange

According to the continuity equation, the velocity of water going into the pipe seems to be the same as the velocity of water coming out. But according to Bernoulli's equation: P a t m + 1 2 ρ v 1 2 + ρ g L = P a t m + 1 2 ρ v 2 2. v 2 = v 1 2 + 2 g L. Which means that the e water would come out faster, which makes much sence.
