The cross section of a healthy vein is 5x10^-5 m^3/s and the volume flow rate of blood in the vein is 5x10^-6 m^3/s. If the cross section of the vein is reduced to 1/3 of the healthy vein cross section, what will be the flow rate of the blood through the narrowed section of the vein. Hint: (use continuity equation of Bernoulli)
