Determine the pump discharge pressure required to adequately supply 300 feet of 5-inch hose that is supplying a manifold from which one 150-foot, 2 1/2-inch attack line is flowing 250 gpm; one 150-foot, 2-inch attack line is flowing 175 gpm; and one 200-foot, 3-inch with 2 1/2-inch coupling attack line is flowing 275 gpm. All lines are equipped with fog nozzles

What will be an ideal response?

162 psi
