Gce Model Questions Vol1 2024 Agricultural Science Question 6
Practice objective / multiple choice question 6 from the 2024 Gce Model Questions Vol1 Agricultural Science examination.
A farmer harvests 10 tonnes of maize with an initial moisture content of 30 % (wet basis). The desired final moisture content for safe storage is 14 %. The drying process follows the model \( \frac{dw}{dt}= -k\,(w-12) \) where \(w\) is the moisture content in % and the ambient moisture is 12 % (wet basis). The rate constant \(k\) is \(0.05\,\text{h}^{-1}\). Determine (a) the time required to reach the target moisture content, and (b) the mass of water removed (in tonnes).
