In a batch drying experiment, a solid with a critical moisture content of 0.2 kg H2O/kg dry solid is dried from an initial moisture content of 0.35 kg H2O/kg dry solid to a final moisture content of 0.1 kg H2O/kg dry solid in 5 h. In the constant rate regime, the rate of drying is 2 kg H2O/(m2.h).
The entire falling rate regime is assumed to be uniformly linear. The equilibrium moisture content is assumed to be zero.
The mass of the dry solid per unit area is_________kg/m2 (round off to nearest integer).
