Blood flow is 83 mL/sec through each capillary. B.) The blood pressure difference across a capillary is 20 mmHg. Assuming that a capillary is about 7um in diameter on average, and that the viscosity of blood is 0.04 poise, calculate the theoretical length of a capillary. C.) The length of a capillary can be measure directly with a microscope and it usually ranges from 0.3 to 1.0 mm. Let us assume that the average length of a capillary is 0.65...
