Igcse Model Questions Vol1 2024 Biology Question 15
Practice objective / multiple choice question 15 from the 2024 Igcse Model Questions Vol1 Biology examination.
Two parallel capillary networks (A and B) have the same length of \(1\ \text{mm}\) and carry blood of viscosity \(\eta = 3.5 \times 10^{-3}\ \text{Pa·s}\). Network A has a radius of \(5\ \mu\text{m}\), while network B has a radius of \(3\ \mu\text{m}\). Assuming laminar flow and that the pressure drop across each network is the same, use Poiseuille's law (flow \(Q \propto r^{4}\)) to determine the ratio of the volumetric flow in network A to that in network B.
