The build-up of plaque on the walls of an artery might decrease its diameter from 1.1 cm to 0.71 cm. The speed of blood flow was 14 cm/s before reaching the region of plaque build up.
1. Discover the speed of blood flow within the plaque region.
2. Discover the pressure drop within the plaque region. (Suppose the density of blood is 1060 kg/m3.)
