Draining a tank (Torricelli’s law) A cylindrical tank with a cross-sectional area of 10 m 2 is filled to a depth of 25 m with water. At t = 0 s. a drain in the bottom of the tank with an area of 1 m 2 is opened, allowing water to flow out of the tank. The depth of water in the tank (in meters) at time t ≥ 0 is d ( t ) = ( 5 − 0.22 t ) 2 . a. Check that d (0) = 25. as specified b. At what time is the tank empty? c. What is an appropriate domain for d ?
