Neco 2025 Agricultural Science Question 8
Practice objective / multiple choice question 8 from the 2025 Neco Agricultural Science examination.
A batch of 500 kg fresh cassava roots has a moisture content of 60\% (wet basis). The roots are sliced into chips and dried in a solar dryer that removes moisture at a constant rate of \(2\) kg h^{-1} per 100 kg of wet chips. The target final moisture content is 12\% (wet basis). After the first 5 hours, the drying rate drops by 20\% because of increased ambient humidity. Determine the total drying time required to reach the target moisture content and the final weight of the dried chips.
