Gce Model Questions Vol1 2019 Geography Question 2
Practice objective / multiple choice question 2 from the 2019 Gce Model Questions Vol1 Geography examination.
A circular drainage pipe runs full under a road. The pipe has an unknown internal diameter \(D\) (in metres). The pipe slope is \(S = 0.001\) (i.e., 0.1 %). The Manning roughness coefficient is \(n = 0.013\). The required discharge is \(Q = 0.12\) m³ s\(^{-1}\). Using Manning's equation, determine the minimum internal diameter \(D\) of the pipe, giving your answer to two decimal places (metres).
