Neco Model Questions Vol1 2024 Agricultural Science Question 19
Practice objective / multiple choice question 19 from the 2024 Neco Model Questions Vol1 Agricultural Science examination.
A farmer harvests \(10{,}000\) kg of fresh cassava roots whose initial moisture content is \(45\)% (wet basis). He wants to dry the roots to a final moisture content of \(12\)% (wet basis). The drying process removes water at a rate of \(0.8\) kg water per hour for every \(100\) kg of fresh cassava being dried, and each dryer can handle at most \(2{,}000\) kg of fresh cassava at a time. Assuming any number of identical dryers can be used simultaneously, determine the minimum number of dryers required and the total drying time (in hours) needed to reach the target moisture content for the whole batch.
