In torr find the (gauge) blood pressure (a) a 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).

Concept explainers

Fluid Pressure

The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.

Gauge Pressure

Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.

3. In a giraffe with its head 2.0 m above its heart, and its heart 2.0 m above its feet, the
(hydrostatic) gauge pressure in the blood at its heart is 250 torr. Assume that the giraffe stands
upright and the blood density is 1.06 × 103 kg/m3 . In torr 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.)
