Question

Consider the flow of blood through a large horizontal artery with 1.0 mm of diameter. The artery has a smooth reduction to an artery 0.5 mm in diameter. If the pressure of the blood in the larger artery is 8.00 x 104 Pa and the pressure in the smaller artery is 6.00 x104 Pa, what is the speed (in m/s) of the blood through the small artery? Assume that the density of blood is 1050 kg/m3.
