A fountain with an opening of radius 0.015 m shoots a stream of water vertically from ground level at 6 m/s . The density of water is 1000 kg/m3 . Calculate the volume rate of flow of water. The fountain is fed by a pipe that at one point has a radius of 0.025 m and is 2.5 m below the fountain’s opening. Calculate the absolute pressure in the pipe at this point. (C) The fountain owner wants to launch the water 4 m into the air with the same volume flow rate. A nozzle can be attached to change the size of the opening. Calculate the radius needed on this new nozzle.
