downcomer piping in ft = Le The frictional pressure drop, psi = 3.36 X 10-s x f Le vi (Wd) 2/di5 (Here, it is assumed that the average flow in each downcomer pipe is d). di is the innerW diameter of the downcomer pipe in inches. f is the friction factor. If there are

Read MoreFrictional resistance within the pipe which in turn is determined by pipe sizing and velocity. Condensation within the pipe All these factors must be considered while designing the distribution network. Steam should be generated from the boiler at rated pressure

Read MoreAs steam condenses in a process, flow is induced in the supply pipe. Condensate has a very small volume compared to the steam, and this causes a pressure drop, which causes the steam to flow through the pipes. The steam generated in the boiler must be
