2. Blood with a hematocrit of 45% flows through a 10 micrometer diameter tube. Flow is directly proportional to the pressure difference across the tube and inversely proportional to the apparent viscosity of blood. Compare the actual pressure difference across the tube with the pressure difference necessary to provide the same flow if the apparent viscosity in the tube remained the same as the apparent viscosity in a very large tube. Discuss implications of the Fahraeus-Lindqvist effect on the work...
