Calculate the pressure of the blood in the brain and in the feet of a pearson when standing. The average pressure of the blood in the heart is 1.3×104N/m2 above atmospheric pressure. The brain is located 0.50 mabove the heart and the feet is located 1.2 mbellow the heart. The density of blood is 1050 kg/m3.
a. Calculate the pressure of the blood in the brain above atmospheric pressure.
b. Calculate the pressure of the blood in the feet above atmospheric pressure.
