a. A granular solid weighing 5000 lb (dried solids) is to be dried under constant drying conditions from a moisture content of 0.20 lb/lb of dried solids to a final moisture content of 0.02 lb/lb of dried solids. The material has an effective area of 0.25 ft/lb of dried solids. The drying rates shown in Table below were previously obtained under the same conditions. Calculate the time required for drying (20 points) Moisture content/ 0.200 200 01:40 0.114 0.096 0,056 0.042 0.000 0.016 Drying to R db/ 0.35 0.35 0.15 0.10 0.265 DINE) 0.150 0.110 0.07 b. Considering the information provided in part a, and considering that the total falling rate period is curved and approximately described by the equation (30 points): N = 2.17X + 0.047 Calculate the falling & total drying time of this process.
