A hospital patient receives a quick 500-cc blood transfusion through a needle with a length of 5.0 cm and an inner diameter of 1.0 mm. if the blood bag is suspended 0.85 m above the height where the blood first starts to flow into the vein, how long does the transfusion take place? Given that the viscosity of blood is 0.017 poise and the density of blood is 1.02 g/cm^3.
