Consider the two lightweight containers shown in FIGURE 15-48. As in the previous problem, these containers have equal forces on their bases but contain different weights of water. This is another version of the hydrostatic paradox.

(a) Determine the net downward force exerted by the water on container 2. Note that the bases of the containers have an area Abase = 24 cm2, the annular region has an area Aring = 18 cm2 and the depth of the water is 18 cm.

(b) Show that your result from part (a) is equal to the weight of the water in container 2.

(c) If a hole is poked in the annular region of container 2, how fast will water exit the hole?

(d) How high above the hole will the stream of water rise?
