A swimming pool is 20 ft wide, 40 ft long, 3 ft deep at the shallow end, and 9 ft deep at its deepest point. A cross-section is shown in the figure. If the pool is being filled at a rate of 1.3 ft3/min, how fast is the water level rising when the depth at the deepest point is 5 ft? (Round your answer to five decimal places.) ft/min
A swimming pool is in the shape of a rectangular parallelepiped (prism) a ft long, b ft wide, and c ft deep. If the pool is full of water, what is the force due to water pressure on one long side of the pool? Assume a = 46 ft, b = 16 ft, c = 8 ft. (Hint: The weight density of water is 62.5 lb/ft3.) (Use decimal notation. Give an exact answer.) F = lbs
