Pumps piped in series or parallel
WebI was trying to show parallel reverse return through the boilers. Those boilers are piped into a secondary distribution system, which is most probably a 2 pipe system (Supply and return, not FLOW, or FEED and return ;-)) I had an employee once who used to call them flow and return, and would mark his pipes with either an F or an R. WebThe volume rate of flow through the pipes in series is the same throughout. Suppose a pipe line consists of a number of pipes of different sizes and lengths. See Fig. 13.37. Let d 1, d …
