Hello,
I want to understand if I can replace a 36in diameter straight pipe, by 2x18in diameter straight pipes, in order to get a similar air flow rate through the system. In reality it seems to me that linear losses are invitable, and are multiplied as I divide the diameter of the pipes. The 2x18in solution would provide a lower flow rate, and at best, the same flow rate than 1x36in. Meaning the best solution is 1x36in, and that's it. But, what kind of losses (small % or significant loss?) are we talking about by switching to 2x18in? That is what I am trying to find out using starccm+. If know there are some empirical formulas about pipe line losses / linear losses through pipes of length L, but I would like starccm+ to help me confirm that, yes, I am actually losing X volume/second in flow rate by multiplying the number of pipes and making each diameter smaller. Did anyone successively run a similar case? thanks! |
