Asample of a food material weighing 10 kg is initially at 450% moisture content dry basis. It is dried to 10% moisture content wet basis. How much water is removed from the sample per kg of dry solids?

The important thing to learn in the question is ' Dry Basis ' and 'Wet Basis' calculation.So when equating the amount of moisture content in percentage,the numerator term remains always same which is the mass of water retained in the solid which is the food material in this case.But the denominator term varies for these 2 cases.For dry basis,we usually have mass of solid only in the numerator while for wet basis we have total mass of solid i.e. (mass of water + mass of dry solid). Wet basis is different from Dry basis in terms of mass addition of water to mass of solid for calculating amount of moisture.

In batching of aggregates the moisture content is expected to be in saturated surface dry condition. However, in a concrete production, the actual moisture content of coarse aggregate on the site just before the batching measured as 8%, and its saturated surface dry condition requires 5% moisture content.
