17 Blood pressure in Argentinosaurus. (a) If this long-necked, gigantic sauropod had a head height of 18 m and a heart height of 8.0 m, what (hydrostatic) gauge pressure in its blood was required at the heart such that the blood pressure at the brain was 80 torr (just enough to perfuse the brain with blood)? Assume the blood had a density of $1.06 \times 10^3 \text{ kg/m}^3$. (b) What was the blood pressure (in torr or mm Hg) at the feet?
