. The stent is cylindrical and is inserted into a blood vessel to treat a prior occlusion. A drug, clopidrogel is coated on the surface of the stent to provide anti-platelet medication to prevent blood clots. The stent is 5 cm long and 1 cm in diameter. If the average blood flow rate velocity is 10 cm/sec, the equilibrium concentration of clopidrogel in the surface of the stent is 100 mg/L, the Diffusion Coefficient of clopidrogel is 5 x 10-6 cm2/sec, the viscosity of blood is 1.2 cP, and the density of blood is 1.054 g/cm3, determine the following: 1. Mass transfer co-efficient 2. Mass transfer rate (j) 3. Cmixed as the blood exits the stent
