Plague builds up on the walls of an artery decreasing its diameter from 1.16 cm to 0.72 cm. If the flow speed is 15.5 cm/s before reaching the region of plague buildup, determine the following. (a) speed at which blood is traveling through the plaque-constricted region (b) pressure change within the plaque-constricted region. (Assume the density of blood is 1050 kg/m?. Be sure to include the appropriate sign with your answer.) 754650 X See if you can adapt Bernoulli's Equation to this situation. What would a positiveegative sign on the pressure difference tell us?
