While visiting the beach, you blow up a balloon to a volume of 3 liters. You then drag the balloon underwater 5 meters, where the pressure is approximately 150,000
Pa. What is the volume of the balloon 5 meters underwater? (You can approximate
1 atmosphere as 100,000 Pa)
0.6 liters
O2 liters
1 liter
4.5 liters
3 liters

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.6 m below the tank bottom which is a = 6.7 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute). report your answer in meters to two decimal places.
