Blood plasma at 37 degrees celsius is to be supplied to a patient at a rate of 2.8*10^-6 m^3/s. If the tube connecting the plasma to the patient's vein has a radius 2.0mm and length 50cm, what is the pressure difference between the plasma and the patient's vein?
(Viscosity blood plasma at 37 degrees celsius is 1.3×10^-3).
