Intravenous infusions are often made under gravity, as shown in the figure.
a) Assuming the fluid has a density of 1.00 g/cm3, at what height h1 should the bottle be placed so the liquid pressure is 58 mm-Hg ?
b) At what height h2 should the bottle be placed so the liquid pressure is 660 mm-H2O ?
c) If the blood pressure is 78 mm-Hg above atmospheric pressure, how high should the bottle be placed so that the fluid just barely enters the vein?
