Neco 2024 Geography Question 30
Practice objective / multiple choice question 30 from the 2024 Neco Geography examination.
A rectangular field has a length of 500 m and a uniform slope of 2% (i.e., \(S = 0.02\) m·m\(^{-1}\)). The Kirpich formula for time of concentration (in minutes) is \(T_c = 0.0195\,L^{0.77}\,S^{-0.385}\), where \(L\) is the slope length in metres.\n\n(a) Calculate the time of concentration for the field.\n(b) The crop being cultivated requires a maximum permissible \(T_c\) of 30 minutes. Determine the greatest possible slope length \(L_{max}\) (in metres) that will still satisfy this requirement on the same slope.
