Gce Model Questions Vol1 2018 Biology Question 8
Practice objective / multiple choice question 8 from the 2018 Gce Model Questions Vol1 Biology examination.
A cylindrical blood‑vessel segment is 0.5 cm long and has an initial radius of 0.02 cm. The blood viscosity is \(3.5\times10^{-3}\) Pa·s and the volumetric flow rate is \(5\times10^{-6}\) m\(^3\) s\(^{-1}\). If vasoconstriction reduces the radius by 20 % while the flow rate remains unchanged, calculate the new pressure drop across the segment (in pascals) using Poiseuille's law.
