Consider blood flowing down an inclined plane. Derive an expression for the velocity profile assuming that blood follows the constitutive equation for a Casson fluid. You can either use a shell balance or the equation of motion in terms of shear stress as your starting point. What is the velocity at x = 0 and at x = xc?
Blood (HD = 0.45 in large diameter tubes) is forced through hollow fiber tubes that are 20 µm in diameter.Equating the volumetric flowrate expressions from (1) assuming marginal zone theory and (2) using an apparentviscosity for the blood, estimate the marginal zone thickness at this diameter. The viscosity of plasma is 1.2 cP.
