A medical technician is trying to determine what percentage of a patient’s artery is blocked by plaque. To do this, she measures the blood pressure just before the region of blockage and finds that it is 1.20 × 10^4 Pa, while in the region of blockage it is 1.15 × 10^4 Pa. Furthermore, she knows that blood flowing through the normal artery just before the point of blockage is traveling at 30 cm/s, and the density of this patient’s blood is 1.06 × 10^3 kg/m^3. What percentage of the cross-sectional area of the patient’s artery is blocked by the plaque? Assume that gravity has negligible effect on the flow of blood.
