Gce Model Questions Vol1 2019 Agricultural Science Question 16
Practice objective / multiple choice question 16 from the 2019 Gce Model Questions Vol1 Agricultural Science examination.
A farmer harvests 10 tonnes of maize with an initial moisture content of 25 % (wet basis). He dries the maize in a dryer where the moisture content M (in %) decreases according to \( \frac{dM}{dt} = -0.5\,(M-14) \) where t is in days. After 3 days the maize is also subject to respiration loss of 2 % of its dry matter per day. Assuming the respiration loss acts on the dry matter present at the start of the drying period, what is the final weight of the maize (in tonnes) after the 3 days, correct to two decimal places?
