I have a question about network flow pressure drop. In a piping system with several identical components in parallel, is the pressure drop across the supply and return header equal to the pressure drop across one of the components? Or is it the inverse of the sum of the inverses? To use numbers for clarity, if you have a supply pipe, A, which feeds pipes B, C, and D, which have components each with a pressure drop of 15 psi, and which feed pipe E, is the pressure difference from pipe A to pipe E 15 psi or 1/(1/15+1/15+1/15) = 5psi? A pressure drop of 15 psi makes more sense to me, but I thought that pipe networks were analogous to electrical circuits such that pressure drop is analogous to resistance.
