Neco 2023 Agricultural Science Question 35
Practice objective / multiple choice question 35 from the 2023 Neco Agricultural Science examination.
A batch of cassava roots weighing 2,000 kg is harvested with an initial moisture content of 65% (wet basis). The farmer wants to dry the roots to a final moisture content of 12% (wet basis) using a solar dryer that removes moisture at a constant rate of 0.8 kg water per hour per 100 kg of fresh weight. During drying, the roots lose dry matter at a rate of 0.2% of the initial dry matter per hour due to respiration. Determine the total drying time required (in hours) to reach the target moisture content, accounting for both moisture removal and dry‑matter loss. Give the answer to one decimal place.
