Force from a Fire Hose

A fireman holds a hose pipe that delivers a stream of water of diameter d at a speed of v. –Give an expression for the volume of water that hits the wall in time t. The density of the water is . –Give an expression for the mass of water that hits the wall in time t. Cross-sectional area of a circle =  r 2 =  d 2 /4

The stream of water hits the wall and then runs down the wall without rebounding. –Give an expression for the change in momentum of the water that hits the wall in time t. –Give an expression for the force exerted by the water on the wall.
