Determine the weight loss of a ton of paddy at 24% if dried to 14%. Correspondingly, determine the price at different level. Considering price difference of P2.00/kg between wet and dry. Make your conclusion from the above figures. 3. From a one hectare farm, 150 bags (50kg/bag) of palay were harvested with moisture content of 26%MCwb. If it will be dry to 14%MC, determine how much water will be removed from drying? 4. One hundred (100) bags of freshly harvested palay was dried to 14%MC and became 90 bags. Determine the fresh moisture content before drying. 5. Two tons of paddy with 22% moisture content on wet basis is to be dried to 13% moisture content on dry basis. Calculate the weight of bone dry products and water evaporated. 6. Determine the quantity of parboiled paddy with 40% moisture content on wet basis required to produce 1 ton of product with 12% moisture content on wet basis. Work out the problem on wet basis and check the answer using dry basis. 7. Draw a graph showing moisture content of grain on wet basis versus moisture content on dry basis. Take the moisture content of grain on wet basis from 10% to 60% at equal intervals of 5%. c.
