2. Capillary tubes can be used in conjunction with a finger stick to draw small amounts of blood from a finger for medical testing. A hemoglobin test that you are using requires at least 10 mm³ of blood. Will a glass tube with a radius of 0.5mm be able to collect enough blood for this hemoglobin test? Assume the capillary tube is held perfectly vertically above the finger during collection and that surface tension is the only force drawing blood into the tube (i.e., ignore any potential pressure differences between the finger and the tube). You may assume blood has the following properties: Density: 1060 kg/m³ Specific Weight: 10400 N/m³ Specific Gravity: 1.06 Coefficient of surface tension: 0.05 N/m Viscosity: 0.005 N-s/m² Contact angle with clean glass: 0° Show all work including free body diagrams.
