Aclosed, rigid tank is filled with water. initially, the tank holds 9.9 ft3 of saturated vapor and 0.1 ft3 of saturated liquid, each at 212°f. the water is heated until the tank contains only saturated vapor. for the water, determine (a) the quality at the initial state, (b) the temperature at the final state, in °f, and (c) the heat transfer, in btu. kinetic and potential energy effects can be ignored.

Foreshadowing. the prologue states that this is the story of "star-crossed lovers." there are four strong foreshadowings of evil in act 1. identify at least two foreshadowings and explain their purpose.

Suppose water is leaking from a tank through a circular hole of area ah at its bottom. when water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cah 2gh , where c (0 < c < 1) is an empirical constant. a tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its bottom. (assume the removed apex of the cone is of negligible height and volume.) (a) suppose the tank is 20 feet high and has radius 8 feet and the circular hole has radius 2 inches. the differential equation governing the height h in feet of water leaking from a tank after t seconds is dh dt = − 5 6h3/2 . if the height of the water is initially 8 feet, how long will it take the tank to empty? (round your answer to two decimal places.)
