(a) Calculate the mass flow rate (in grams per second) of blood (ρ = 1.0 g/cm3) in an aorta with a cross-sectional area of 2.0 cm2 if the flow speed is 33 cm/s.
Answer is in g/s
(b) Assume that the aorta branches to form a large number of capillaries with a combined cross-sectional area of 3.0 103 cm2. What is the flow speed in the capillaries?
Answer ins in cm/s
