A fire truck is being designed to deliver 1250 gal/min of water at 100°F. The input comes from a suction hose inserted into a lake, a river, or a pond. The discharge is to a water gun mounted on the truck that requires 150 psi at its nozzle. The water source could be up to 200 ft from the truck and 10 ft below the roadway. The pump will be mounted on a platform at the middle of the truck, at a height of 40 in above the roadway. The connection to the water gun is 6.5 ft above the pump. Specify the suction hose size, the design of the rigid piping connecting the hose to the pump inlet, the discharge piping to the water cannon, valves, and other fittings.
