Question

3. a. Consider blood plasma with protein volume fraction of 9%. Estimate the viscosity of the plasma. Use viscosity of water as 0.69 mPa.s . b. Consider a person with polycythemia(elevated RBC concentration) of 60%. Determine the yield stress and Newtonian viscosity of this person’s blood. c. Consider this person’s aorta of diameter 3cm. The flow rate is 5 liters/min, determine the pressure gradient (pressure difference per unit length). Use non-Newtonian rheology of blood based on Casson equation. d. Use the flow rate to determine the average velocity and Reynold’s number. Use effective viscosity as ratio of shear stress to shear rate. Use density of blood as 1050 kg/ m³. e. Find entrance length for flow entering this artery.
