Flow and Pressure in Pipes Explained — Practical Engineering

Apr 6, 2021At 0.3 gpm, we see pressure drop across the pipe is practically negligible, just under half an inch. At 0.6 gpm, the head loss is about an inch. And, at 0.9 gpm, the head loss is just over 3 inches. Now I'm changing out the sample for a much longer pipe of the same diameter. In this case, it's 20 times longer than the previous example.
