A 150-lb fireman is holding a hose which has a nozzle diameter of 1 inch and hose diameter of 2 inches.
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. yw = 62.4 lb/ft3 .
