Design Velocity - an overview ScienceDirect Topics

Design velocity and spacing for convective heat transfer surfaces can be seen in Table 5.5.If we place tubes close to each other and use high flue gas velocity, then the propensity to foul and erode is high. Especially with biofuels there is a need to utilize moderate flue gas velocities and have ample spacing.

Fluid velocity in a vertical pipe - Physics Stack Exchange

Jan 21, 2017  1. Consider a pipe with length L and uniform radius A is held vertically. 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.
