But now, let's add 15' of 1" hose. The pump now has to overcome the friction loss of the 1" pipe before the SCWD. So now the SCWD probably only sees 6500 lph. If you can lower the friction loss the water encounters on the way (make it easier for it to get there) to the SCWD, the pump will perform much better. I tried using some of my firefighting pump formula's but the pressures are too small for them to work, but the principles are the same. Larger hose for longer lengths to get the same pressures and volumes. |
