A nozzle is attached to a fire hose by a bolted flange. The pressure at the flanged joint is 100 psig and the cross-sectional area of the hose at the flange is 10 in2. The area of the outlet nozzle is 1 in2 and the outlet velocity of water through it is 122.6 ft s-1. Calculate the force tending to tear apart the flange.
