An elephant has an aorta that is approximately 8cm in diameter and a resting heart beat of 35 beats /min. Assume that the velocity across the aortic valve is 1m/s. a) Calculate the Reynolds number (1 pt). Classify the flow regime (1 pt). b) Calculate the Womersley's number (2 pts). Can we ignore unsteadiness? (1 pt) Consider a blood density of 1060Kg/m3 and a dynamic viscosity of 3.5cP
