Neco Model Questions Vol1 2022 Agricultural Science Question 44
Practice objective / multiple choice question 44 from the 2022 Neco Model Questions Vol1 Agricultural Science examination.
A batch of \(500\) kg fresh cassava chips has an initial moisture content of \(55\)% (wet basis). The target moisture content for storage is \(12\)% (wet basis). A drying kiln removes water at a rate of \(0.8\) kg h⁻¹ per kW of thermal power supplied. The kiln operates at a thermal efficiency of \(70\)% and uses fuel with a calorific value of \(18\) MJ kg⁻¹. Determine the minimum thermal power (in kW, rounded up to the nearest whole kW) required to achieve the desired moisture reduction in \(8\) hours, and the corresponding amount of fuel (in kilograms, to one decimal place) that must be burned.
