A medical technician is trying to determine what percentage of apatient's artery is blocked by plaque. To do this, she measures theblood pressure just before the region of blockage and finds that itis 1.20×104 Pa , while in the region of blockage it is1.15×104 Pa . Furthermore, she knows that blood flowingthrough the normal artery just before the point of blockage istraveling at 27.5 cm/s , and the specific gravity of this patient'sblood is 1.06.
Part A: What percentage of the cross-sectional area of thepatient's artery is blocked by the plaque?
