Distribution pipe with non standartized decreasing diameters in settling tanks

Description

Determines non standardized diâmeters for the pipe sections, that assure equal velocities in all of them. Two calculations possibilities are offered: (a) from each section, two exit pipes emerge, or (b) une exit pipe emerges. Given: the water temperature, the flow to be distributed, the number of sections (up to 12) the upstream section diameter, the exit pipes diameter and the pipes internal roughness, determines: a) the flow, velocity and velocity gradient for each exit pipe; for each section of the distribution pipe: the flow, diameter, velocity and velocity gradient.
