Concept

Problem: A patient is to be given a blood transfusion. The blood is to flow through a tube from a raised bottle to a needle inserted in the vein. The inside diameter of the 26-mm-long needle is 0.81 mm, and the required flow rate is 2.3 cm3 of blood per minute. How high h should the bottle be placed above the needle? Assume the blood pressure is 78 torr m torr above atmospheric pressure.
