a drinking fountain projects water at an initial angle of 50 degrees above the horizontal and the water reaches a maximum height of 0.150 m above the point of exit. assume air resistance is negligible. calculate the speed at which the water leaves the fountain. the readius of the fountain's exit hole is 4 x 103 m. calculate the volume rate of flow of the water. the fountain is fed by a pipe that at one point has a radius of 7 x 103 m and is 3 m below the fountain's opening. the density of water is 1 x 10+3 kg/m3. calculate the gauge pressurte in the feeder pipe at this point.
