The heart of the standard adult pumps 5 liters of blood (with a
density of 1030 kg/m3 ) per minute into the aorta: a) What is the
volume flow rate (in cm3 /s ) in the cardiovascular system? b) What
is the speed of the blood in the aorta given that its diameter is
2.2 cm. c) At some regions of the aorta there is stenosis (due to
the deposition of plaque) and the diameter is decreased by 30%.
Ignoring the viscosity of blood and assuming laminar flow calculate
the speed of blood flow at the stenosis
