Chapter 6, Problem 6RQ
- 6. Neglect the weight of the drum in the following problem. A sealed cylindrical drum has a diameter of 6 feet and a length of 12 feet. The drum is filled exactly half-full of a liquid having a density of 90 pounds-mass per cubic foot. It is resting on its side at the bottom of a 10-foot-deep drainage channel that is empty. Suppose a flash flood suddenly raises the water level in the channel to a depth of 10 feet. Determine if the drum will float. The density of water is 62 pounds-mass per cubic foot.
