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 4.0-cm-long needle is 0.40 mm, and the required flow rate is 4.0 cm 3 of blood per minute. How high h should the bottle be raised above the needle? Assume the blood pressure in the vein is 18 torr above atmospheric pressure.
