Neco 2024 Agricultural Science Question 44
Practice objective / multiple choice question 44 from the 2024 Neco Agricultural Science examination.
Fresh cassava chips weighing 500 kg (wet basis) have an initial moisture content of 45 % (wet basis). The target moisture content for storage is 12 % (wet basis). The chips are dried in a continuous dryer that receives air at 30 °C and 60 % relative humidity, flowing at 2 m³ s⁻¹. Assume atmospheric pressure 101.3 kPa, air density 1.2 kg m⁻³, specific heat of air 1.005 kJ kg⁻¹ K⁻¹ and latent heat of vaporisation 2450 kJ kg⁻¹. The outlet air is assumed to be saturated at 30 °C. Neglect heat losses. Estimate the drying time required (in hours) to reach the target moisture. Give your answer to one decimal place.
