Flat velocity profile
WebIf we assume that the fluid enters the tube from a reservoir, the profile at the inlet is virtually flat. The transition from a flat velocity distribution, at the entrance of a tube, to the fully developed parabolic velocity profile is illustrated in Figure 16.13. Once inside the tube, the layer of fluid immediately in contact with the wall ... WebOnce the fully developed velocity profile is established, the metal pipe is replaced by a pipe, cast from benzoic acid, of the same inside diameter. If the length of the pipe made …

WebTranscribed Image Text: 1. Near the surface of a flat plate, water has a velocity profile given by v, = Vo8 y-3 y with y in mm, V, in cm/s, and 0 WebIn this region the velocity profile is defined by the stress-relation given in (7). We substitute the definition given in (6) into (7) and use the approximation ∂u/∂y ≈ u/y to solve for the velocity profile. Laminar Sub-Layer [y < δs = 5 ν / u*]: u(y) = u* 2 y / ν (11) Above the Laminar Sub-Layer (y > δs) the velocity profile is ...
