Blood is flowing through a bundle of hollow fiber tubes that are each 50 μm in diameter. There are 10,000 tubes in the bundle. The hollow fiber tube length is 12 cm and the pressure drop across each tube is found to be 250 mmHg. The hematocrit of the blood is 0.40. The blood flow rate for these conditions is 80 μL/h in each tube. Estimate the marginal zone thickness, the hematocrit of the core, and the tube hematocrit
