A drinking fountain shoots water about 14 cm up in the air from a nozzle of diameter 0.51 cm . The pump at the base of the unit (1.1 m below the nozzle) pushes water into a 1.2 cm diameter supply pipe that goes up to the nozzle.What gauge pressure does the pump have to provide? Ignore the viscosity; your answer will therefore be an underestimate.

    Water is delivered to a 4.0 cm diameter fountain head from a 6.9 cm diameter pipe that is 3.4 m below the fountain head and at a pressure of 94 kPa. The fountain head shoots the water straight up into the air. Neglect all losses. a.) What is the velocity of water coming out of the fountain head? Hint: Must use Bernoulli AND Continuity b.) What is the volume flow rate of the water through the fountain head? Hint: Q=vA
