Question

An artery in a human body can be narrowed down by an arteriosclerotic plaque, causing heart problems. Suppose one segment of a horizontal artery is narrowed down to 1/4 of its normal cross-sectional area. The blood flows at 0.166 m/s in a healthy segment. Assume that blood is an incompressible and non-viscous fluid. (a) At what rate does the blood flow in the constricted segment? (b) By how much does the pressure increase in the constricted segment relative to the healthy segment?
