Engr. Dabbie A. Abe, M.Sc was tasked to design a biomass-fed co-dryer for a DOST-PCIEERD funded project. The drying system he proposed can produce 2200 lb of co-processed dried sorghum and corn, both at 10% MCdb. Sorghum's fresh weight was about 25% Mdb while Corn's fresh weight was 30% MCwb. Due to high volume of rice hull in Engr. Abe's area, he utilized it as feedstock source of energy in his dryer. He estimated a calorific value 3,000 kcal/kg for the feedstock. Assume an ambient temperature within the drying facility at 22 degree Celsius while it has a perimeter of 23 yards (1) Compute for the drying facility pentagonal area knowing that it is inscribed in a 5-m radius (2) Compute for the biomass:water evaporated ratio (3) Mass of sorghum (4) Mass of corn (5) Convection within the drying system 's free air using convective heat transfer coefficient of 1 BTU*h^-1*ft^-2*R^-1
