A drinking fountain projects water at an initial angle of 50 degrees above horizontal Water reaches maximum height of 0.150m above point of exit. The fountain is fed by pipe that has radius of 7.00 x 10^-3 m and is 3.00 m below fountain's opening. Density of water is 1.0 x 10^3 kg/m^3 Calculate gauge pressure in feeder pipe at this point. Explain how you get velocity of water at this point.
