Flow visualisation and velocity measurements in a vertical

Oct 01, 2003 The tangential velocity profiles shown in Fig. 5 are similar to the expected flow within a cyclone in that they increase rapidly from near the inner tube to a maximum velocity, then gradually decrease, while remaining positive in sign, with increasing radii. Analysis of the velocity measurements in the inner core confirms that the relationship between the tangential velocity and radius is indeed

Fluid velocity in a vertical pipe - Physics Stack Exchange

Jan 21, 2017 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
