Waec Model Questions Vol1 2024 Agricultural Science Question 50
Practice objective / multiple choice question 50 from the 2024 Waec Model Questions Vol1 Agricultural Science examination.
Fresh cassava chips have an initial moisture content of 55 % (wet basis). They are to be dried to a final moisture content of 12 % (wet basis). The drying follows the law M(t) = M_eq + (M₀ - M_eq) e^{‑k t}, where M(t) is moisture content at time t (hours), M_eq = 10 % (wet basis), M₀ = 55 % (wet basis) and k = 0.25 h⁻¹.\n(a) Calculate the drying time required to reach the target moisture content of 12 % (wet basis).\n(b) If the initial mass of the chips is 2 000 kg (wet basis), determine the final total mass of the product after drying to 12 % moisture.
