WebSep 1, 2024 · So, you can see the importance of friction loss measurement. Another reason measurements are so important is that standard industry estimates for FL … WebSep 12, 2024 · Friction loss in 1 3/4-inch hose for 150 gpm is about 28 psi per 100 feet of hose. The answer: PDP = 100 + (2 x 28); PDP = 100 + 56; PDP = 156. To flow 150 gpm …
Hand Method for Calculating Friction Loss for Firefighters
WebJan 17, 2000 · 01-14-2000, 06:40 PM. The answer reflects the amount of pressure (psi) lost due to friction loss. That amount of pressure however, is directly affected by the amount (gpm) of water flowing through the hose. So, the higher the flow, the greater the friction loss. Try the formula with various volumes of water being flowed, and the principle ...
