State blood inlet tubing and blood outlet tubing

Reference no: EM13194096

In a hemodialyzer (artificial kidney), blood (density =1.06 g/cm^3) flows through a bundle of hollow fibers, a salt solution flows around the outside of the fibers, and waste products transfer from the blood through the fiber walls to the soluion. A typical blood flow rate through a hemodialyzer is 350cm^3/min and the associated friction of flow is 45000 cm^2/s^2. The hemodialyzer is 30cm long (between the blood inlet and blood outlet), and the blood inlet tubing and blood outlet tubing have the same diameter. What is the blood pressure drop (in units of mm Hg) from inlet to outlet if the hemodialyzer is oriented

a) Horizontallly (with the blood inlet and blood outlet at the same height)?

b) Vertically with the blood inlet at the bottom and blood oulet at the top?

c) Vertically, with the blood inlet at the top and the blood outlet at the bottom?
