Bulk velocity equation
WebIn reality this is a combination of diffusion and bulk motion of molecules. Near the surface the fluid velocity is low, and diffusion dominates. At distance from the surface, bulk motion increases the influence and … WebThe velocity of any wave is related to its frequency and wavelength by v = f λ, 17.3 where v is the speed of the wave, f is its frequency, and λ is its wavelength. Recall from Waves …
