Pressure Drops In Pipes: Part 2, Series and Parallel

This is Part 2 in a series on pressure drops in pipes. Part 1 covered the basic concepts and equations (1-4b). It is recommended to read that before proceeding, or to have it open along side this article for reference.

Symmetrical Parallel Pipes

A single pipe is not usually sufficient to solve a real—life problem. Instead, systems of pipes, often quite complex, are used to achieve all desired results. The math, as a result, becomes more difficult, but where would be the fun if it was easy?
