6. Estimate the force acting on a white blood cell as it adheres to the blood vessel wall in a post capillary venule. Please note that the appropriate Reynolds number to use is one based on the cell and not the Re for the flow in the vessel. Also, make sure to use the velocity of the flow near the cell rather than the average velocity of the flow since the flows moves much more slowly near the wall. A good estimate for the force on a small spherical particle moving in a fluid is given by Stoke's Law
