Holes in Pipes 2


A barrel of water with radius of 2.0 m sits on top of an 8-meter-high wall. A hole of radius 1 cm forms about 5 m down from the level of the water in the barrel. What is the velocity of the water as it leaves the hole? Use a water flow approach. Remember that Bernoulli’s equation is:
p1 + pgy1 + (1/2)pv12 = p2 +pgy2 + (1/2)pv22
