A food processor consists of an upper "storage tank" and lower "collection bin". The upper chamber has a diameter D and contains unprocessed food which has a constant density PA. The processed food with constant density pF falls into the collection bin, which has a diameter d. Using a closed system consisting of only the unprocessed and processed food, find an expression for the time rate of change of the height of the processed food in the collection bin, dh/dt. Use symbols only - express the answer in terms of PA, PF, D, d, H, and h. You may assume that the mass of the falling food is negligible and that the food is tightly packed in the storage tank and collection bin (i.e., there is no empty space to worry about).

A ship of displacement 36000 tonne carries oil fuel in four tanks 16.0 m long and 6.0 m broad, the tanks arranged with their length in the fore and aft direction. The specific gravity of the oil is 0.84, and the density of seawater inwhich the ship is floating is 1020 kgm-3. For a ship of this size, the metacentric height is at least 500 mm. What is the reduction of the metacentric height of the ship because of the oil that is contained in the tanks and how serious is this reduction? Please discuss further your conclusions.
