Neco 2022 Agricultural Science Question 50
Practice objective / multiple choice question 50 from the 2022 Neco Agricultural Science examination.
A batch of \(2{,}000\) kg fresh cassava chips has an initial moisture content of \(55\%\) (wet basis) and must be dried to \(12\%\) moisture (wet basis). The dryer removes moisture at a rate given by \(R = 0.8\,(W - W_{\text{target}})\) kg·h\(^{-1}\), where \(W\) is the current water mass (kg) and \(W_{\text{target}}\) is the final water mass. Assuming the drying process is considered complete when the water mass is within \(1\%\) of the target water mass, calculate the minimum drying time required, in hours, to one decimal place.
