The Womersley number (a) is a dimensionless number in biofluid mechanics and biofluid dynamics. It is a dimensionless expression of the pulsatile flow frequency in relation to viscous effects in blood flow and is given by the expression below. a = L Where L is the radius of the artery or vein w is the frequency of the oscillations 1.1 For a human research subject, the heart rate is 70 beats per minute, the radius of the aorta (the largest artery in the human body) is 12.5 mm. Calculate the Womersley number for the aorta. Assume density of blood to be 1060 kg/m³ and dynamic viscosity to be 3 x 10° Pars In order to study the flow in the aorta in an in vitro experimental setup, a flow model that is double in size using the water as the experimental fluid. What would the "beats per minute" required in the experiment? 1.2 Assume density of water to be 1000 kg/m³ and dynamic viscosity to be 8.9 x 104 Pa-s The Womersley number (a) is a dimensionless number in biofluid mechanics and biofluid dynamics.
