Example 2/YF) (The Great Molasses Flood) On the afternoon of January 15, 1919, an unusually warm day in Boston, a 17.7 m high 27.4 m diameter cylindrical metal tank used for storing molasses ruptured. Molasses flooded into the streets in a 5 m deep stream, killing pedestrians and horses and knocking down buildings. The molasses had a density of 1600 kg/m. If the tank was full before the accident, what was the total outward force the molasses exerted on its sides? (Hint: Consider the outward force on a circular ring of the tank wall of height dy and at a depth Huy below the surface. Assume that before the tank ruptured, the pressure at the surface of the molasses was equal to the air pressure outside the tapk) 2 Patm Plys: Patm tag y difret Paret dA = Pret C-dy.
