A bug from South America known as Rhodnius prolixus extracts the blood of animals. Suppose Rhodnius prolixus extracts 0.300 cm3 of blood in 25.0 min from a human arm through its feeding tube of length 0.200 mm and radius 5.00 µm. What is the absolute pressure at the bug's end of the feeding tube if the absolute pressure at the other end (in the human arm) is 106 kPa? Assume the viscosity of blood is 0.00130 Pa-s. 318 kPa
