Neco 2021 Agricultural Science Question 15
Practice objective / multiple choice question 15 from the 2021 Neco Agricultural Science examination.
A farmer stores \(1.5\) tonnes of maize in a hermetic bag. The initial moisture content is \(13\%\) (wet basis). During storage the moisture content follows first‑order kinetics: \(\frac{dM}{dt} = -k\,(M-M_{eq})\), where \(M\) is moisture percentage, \(M_{eq}=12\%\) is the equilibrium moisture at the storage temperature, and \(k=0.05\) day⁻¹. Determine the moisture content after \(10\) days and state whether the grain meets the safe‑storage limit of \(\le 13\%\) moisture. Give the moisture content to two decimal places.
