Glucose, during transfusion, flows from a bag through a needle that is 3.0cm long and has an inside diameter of 0.50 mm. If the transfusion rate is to be 0.50 l in 40 min, how high above the needle must the bag be held? Assume a density of 1040 kg/m3 and a coefficient of viscosity of 2.25 x 10-3 N.s/m2 for the glucose. Assume that the patient's blood is nearly at atmospheric pressure. Calculate the following: 

a) Flow rate in m3/s

b) Height
