A drinking fountain projects water at an initial angle of 50° above the horizontal, and the water reaches a maximum height of 0.150 m above the point of exit. Assume air resistance is negligible. 1. Calculate the speed at which the water leaves the fountain 2. The radius of the fountain’s exit hole is 4 x 10-3 m. Calculate the volume rate of flow of the water 3. The fountain is fed by a pipe that at one point has a radius of 7 x 10-3 m and is 3 m below the fountain’s opening. Calculate the gauge pressure in the feeder pipe at this point.
