Elving Circus of Physics Giraffe bending to drink. In a giraffe with its head 1.98 m above its heart, and its heart 1.89 m above its feet, the hydrostatic) gauge pressure in the blood at its heart is 234 torr. Assume that the giraffe stands upright and the blood density is 1.0610% kg/m. In torr for mm Hg), find the (gauge) blood pressure (a) at the brain (the pressure is enough to perfuse the brain with blood, to keep the giraffe from fainting) and (b) at the feet (the pressure must be countered by tight-fitting skin acting like a pressure stocking). (c) If the giraffe were to lower its head to drink from a pond without splaying its legs and moving slowly, what would be the increase in the blood pressure in the brain? (Such action would probably be lethal.) (a) Number Units (b) Number Units (c) Number i Units
A fish maintains its depth in fresh water by adjusting the air content of porous bone or air sacs to make its average density the same as that of the water. Suppose that with its air sacs collapsed, a fish has a density of 1.06 g/cm? To what fraction of its expanded body volume must the fish inflate the air sacs to reduce its density to that of water?
