The 150-lb fireman is holding a hose which has a nozzle diameter of 1 in and hose diameter of 2 in. If the velocity of the water at discharge is 60 ft/s, determine the resultant normal and frictional force acting on the man’s feet at the ground. Neglect the weight of the hose and the water within it. Yv = 62.4 lb/ft3. |
