If the blood vessels in a human being acted as simple pipes (which they do not in actual), what would be the difference in blood pressure between the blood in a 1.80 m tall man's feet and in his head where he is standing? Assume the specific gravity of blood to be 1.06.
(a) 16.23 Kpa
(b) 18.7 KPa
(c) 17.3 KPa
(d) 15.9 KPa
