Physics: Mass Flow Rate
(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 31 cm/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?
