Which Supply Line? - Firefighter
Which Supply Line? Last week, I addressed handlines. With 200 psi, you can flow 1,000 gpm beyond 4,000 feet. (Note: 300 psi 4- and 5-inch hose is also available.) Also, the 3-inch hose has 2.1 more square inches of area than a 2.5-inch hose; consequently, the 3-inch flows almost 1.5 times more water than the 2.5-inch hose.
