A patient is to be given a blood transfusion. The blood is to flow through a tube from a raised bottle at atmospheric pressure to a needle inserted in the vein which the pressure is 18 mmHg higher than atmospheric. The inside diameter of the 3.2 cm long needle is 0.603 mm and the required flow rate is 4.2 mL per minute. How high should the bottle be placed above the needle? For blood, n = 0.0040 Pa-s and p = 1050 kg/m³. Take g = 9.8 m/s².
