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 13 kPa while in the region of blockage it is 12 kPa. Furthermore, she knows that blood flowing through the normal artery just before the point of blockage is traveling at 0.32 m/s, and the specific gravity of this patient’s blood is 1.06. What percentage of the cross-sectional area of the patient’s artery is blocked by the plaque?
