Ear "popping" is an unpleasant phenomenon sometimes experienced when a change in pressure occurs, for example in a
fast-moving elevator or in an airplane. If you are in a two-seater airplane at 3000 m and a descent of 100 m causes your
ears to "pop," what is the pressure change that your ears "pop" at, in millimeters of mercury? If the airplane now rises to
8000 m and again begins descending, how far will the airplane descend before your ears "pop" again? Assume a U. S.
Standard Atmosphere.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
