1. If the human aorta has a cross-sectional area of 2.5 cm2 and the flow speed of blood in the aorta is 30 cm/s while the density of blood is 1.05 g/cm3.
a. Calculate the mass flow rate of blood (in g/s) in the aorta
b. Assume that the aorta branches to form a large number of capillaries with a combined cross-sectional area of 400 cm2, what is the flow speed in the capillaries?
