$($Geankoplis $9\mathrm{.}6-211\mathrm{.}34$kg blanched corns are dried in a pan of $0\mathrm{.}4570\mathrm{.}457m$ from an initial moisture content of $78\%($wet weight basis$)$ to the critical moisture content of $2\mathrm{.}4kgH2O\frac{?}{kg}$ dry solid. The material is $25\mathrm{.}4mm$ deep in the pan, and the sides and bottom can be considered to be insulated. Heat transfer is by convection from an air stream flowing parallel to the surface at a velocity of $3\mathrm{.}05m/$s$.$ The air is at $65\mathrm{.}6C$ and has a humidity of $0\mathrm{.}010kgH2O\frac{?}{?}kg$ dry air. Predict the drying rate and drying time in the constant rate period. $(1\mathrm{.}951(kg)H2O\frac{?}{h}{m}^2,7\mathrm{.}0(h))$
