Determine the total pressure loss due to friction and elevation pressure for a hoseline assembly in which one 300 foot, 3-inch hose with 2 1/2-inch couplings is supplying two attack lines. The first attack line consists of 200 feet of 1 3/4-inch hose that is stretched through the front door of a structure. The first attack line is flowing 150 gpm. The second attack line is 200 feet of 2-inch hose that is carried up a ground ladder and stretched through a second floor window. The second line is flowing 200 gpm.
