Problem 69GP

Giraffes are a wonder of cardiovascular engineering. Calculate the difference in pressure (in atmospheres) that the blood vessels in a giraffe's head must accommodate as the head is lowered from a full upright position to ground level for a drink. The height of an average giraffe is about 6 m.

ANSWER:

Solution 69GP:

Fluid always flow from high pressure to low pressure. We have to determine the pressure difference that the giraffe's head must accommodate as the head is lowered from a full upright position to ground level for a drink.
