Problem 6 (total: 20 points) Answer the following questions: (a) Describe the Fåhræus-Lindqvist effect. At what radii is this effect more pronounced? (2.5 points) (b) What causes the Fåhræus-Lindqvist effect? (2.5 points) In an experiment demonstrating the Fåhræus-Lindqvist effect, bovine blood (with Hematocrit (H) of 0.40 and plasma viscosity of 0.0012 Pa.s) is flowed between two beakers through a glass capillary tube with diameter (D) of 100 µm and length (L) of 1 mm. The pressure difference (Ap) across the capillary tube is maintained at 10 kPa. (c) The blood flow rate (Q) is measured to be 0.01 cm³/s. Determine the effective viscosity ($\mu_{eff}$) of the blood flowing in the capillary tube. (5 points) (d) If feed reservoir hematocrit is reduced to zero, what will be the blood flow rate (Q) across the pipette (in cm³/s)? Assume the same glass pipette and pressure difference. (5 points) (e) Briefly describe how the effective viscosity will change if the capillary radius is gradually reduced. Draw a schematic showing the $\mu_{eff}$ with capillary diameter (H = 40%). (5 points) Beaker 1 Diameter = 0.1 mm Length = 1 mm Beaker 2 Figure 6. Observation of Fåhræus-Lindqvist effect in a capillary tube.
