Waec Model Questions Vol1 2025 Agricultural Science Question 19
Practice objective / multiple choice question 19 from the 2025 Waec Model Questions Vol1 Agricultural Science examination.
Fresh cassava chips have an initial moisture content of 60 % (wet basis). They are to be dried in a solar dryer until the moisture content reaches 12 % (wet basis). The equilibrium moisture content under the drying conditions is 10 % (wet basis) and the drying follows first‑order kinetics described by MR = e^{‑k t}, where MR = (M - M_eq)/(M₀ - M_eq) and k = 0.15 day⁻¹. To two decimal places, how many days are required to reach the target moisture content?
