Neco Model Questions Vol1 2019 Biology Question 47
Practice objective / multiple choice question 47 from the 2019 Neco Model Questions Vol1 Biology examination.
Blood flow through a cylindrical vessel follows Poiseuille's law: \(Q = \frac{\pi \Delta P r^{4}}{8 \eta L}\). Two vessels, A and B, have the same pressure difference \(\Delta P\) and blood viscosity \(\eta\). Vessel A has radius \(r_{A} = 2\ \text{mm}\) and length \(L_{A} = 30\ \text{cm}\); vessel B has radius \(r_{B} = 1\ \text{mm}\) and length \(L_{B} = 20\ \text{cm}\). What is the ratio of the flow rate in vessel A to that in vessel B (\(Q_{A} : Q_{B}\))?
