The pressure within a droplet of blood with radius r=0.1 mm in air under normal conditions is 1.010 bar. a) Calculate the surface tension of blood (with respect to air). b) At a blood pressure of 110 mm Hg (760 mm Hg = 1 bar), 12 mL blood exits the body in a tube of length L=20cm and a diameter of 1 mm within now minute. Calculate the viscosity of that blood.
