West Mead #1 crews trained this evening on water supply and water movement. The crews were given the scenario to achieve the highest flow possible with our water supply engine (28-11).

Review of assignments and friction loss

While discussing the scenario, the crews also reviewed friction loss (how much pressure we lose pushing water through hose) and engine pressures.

Two 4" lines supplying 28-12 and 28-13

28-11’s crew set up a draft from French Creek with the engine and supplied 705 gallons per minute to 28-13 while at the same time delivering 814 gallons per minute to 28-12.

Crews then experimented with adding the portable pumps carried on 28-11 to the equation. Each pump is rated at 500 gallons per minute under ideal conditions. With both pumps running along with 28-11 drafting the crew achieved a water supply that generated in excess of 2,100 gallons per minute.
