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 34 mm long needle is 0.96 mm, and the required flow rate is 3.0 cm3 of blood per minute. How high h should the bottle be placed above the needle? Use \rho blood = 1.05\times 10^3kg/m3, \eta blood = 4.0\times 10^-3Pa·s. Assume the blood pressure is 64 torr above atmospheric pressure.
