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
