Neco 2017 Agricultural Science Question 35
Practice objective / multiple choice question 35 from the 2017 Neco Agricultural Science examination.
Cassava chips are dried in a solar dryer. The initial moisture content (wet basis) of the chips is 45%. The desired final moisture content is 12% and the equilibrium moisture content of the dryer is 10%. The drying follows Newton's law of drying: \(M(t) - M_e = (M_0 - M_e) e^{-kt}\), where \(M(t)\) is the moisture content at time \(t\) (in hours), \(M_0\) is the initial moisture content, \(M_e\) is the equilibrium moisture content and \(k = 0.15\) h\(^{-1}\). Calculate the drying time required to reach the target moisture content, giving your answer to one decimal place in hours.
