Nutrient media is flowing at a rate of 1.5 L min in a tube that is 5 mm in diameter. The walls of the tube are covered with antibody-producing cells, and these cells are anchored to the tube wall by their interaction with a special coating material that was applied to the surface of the tube. If one of these cells has a surface area of 500 um², what is the amount of force that each cell must resist as a result of the flow of this fluid in the tube? Assume the viscosity of the nutrient media is 1.2 cP=0.0012 Pa sec.
