1. Describe how to calculate flow-induced shear stress on endothelial cells. (5%) 2. The blood flow through a large artery of radius 2.5 mm is found to be 20 cm long. The pressure across the artery ends is 380 Pa, calculate the blood's average speed. (10%) 3. You are designing a hollow fiber unit. The fiber diameter is 800 µm and their length is 30 cm. You want a flow rate of 8 mL/min for each fiber. What should be the pressure drop in mmHg across each fiber length to achieve this flow rate? (10%) 4. What differences would you expect to observe between a random walk of a molecule in a gas and a random walk of a protein molecule in water (explain in detail)? (10%) 5. You are given a disk of biopsied (cartilage) tissue (3 mm diameter and 1 mm thickness) and a concentrated solution of fluorescent solutes (molecular weight 10 kDa) and are asked to determine the partition coefficient of that solute within the tissue sample. Assume you have a well-equipped laboratory at your disposal. How do you proceed? (15%)
