WebQuestion: Assume that whole blood with a hematocrit of 45% flows through a small diameter tube. The total flow rate is 16 cc/s, although in the core region it is 12 cc/s and in the peripheral region it is 4 cc/s. The blood cells accumulate in the core region with a volume of 10 mm' and there are no blood cells present in the cell-free peripheral region which has a WebFor small vessels, the lower effective viscosity results in a higher optimal hematocrit, reaching the optimal value of more than 0.5 for vessel diameters below 50 μm.
