Neco 2023 Agricultural Science Question 17
Practice objective / multiple choice question 17 from the 2023 Neco Agricultural Science examination.
A batch of 500 kg fresh cassava chips has an initial moisture content of 60\% (wet basis). During drying, moisture is removed at a constant rate of 5 kg h\(^{-1}\) while the moisture content is above 30\%; once the moisture content reaches 30\% or lower, the removal rate halves to 2.5 kg h\(^{-1}\). Determine (a) the total drying time required to achieve a final moisture content of 20\% (wet basis) and (b) the final weight of the dried chips. Give the drying time to one decimal place (hours) and the final weight in kilograms.
