WebFeb 20, 2024 · We need to compare the artery radius before and after the flow rate reduction. Solution With a constant pressure difference assumed and the same length and viscosity, along the artery we have Q1 r4 1 = Q2 r4 2 So, given that Q2 = 0.5Q1, we find that r4 2 = 0.5r4 1. Therefore, r2 = (0.5)0.25r1 a decrease in the artery radius of 16%.
