Q1: Blood, during transfusion, flows from a bottle through a needle that is 3.5cm long and has an inside diameter of 0.6mm. How high above the needle must the bottle be held in order to transfuse 0.5L of blood in 40min? The density of whole blood is 1050 kg/m3 and the viscosity is 2.7X10-3 N•s/m2 . Assume the patient’s blood is nearly at atmospheric pressure.
