A cellulosic ethanol plant receives two types of round bales; 60% of bales are 1.5m × 1.2m (diameter by length) and 40% of bales are 1.8m × 1.5m. The average bulk density of all bales is 105kg/m3. a....

A cellulosic ethanol plant receives two types of round bales; 60% of bales are 1.5m × 1.2m (diameter by length) and 40% of bales are 1.8m × 1.5m. The average bulk density of all bales is 105kg/m3. a. Determine the number of bales required to operate the biorefinery 325 days/ year if the daily consumption is 1500 tons/day. b. Determine the % of material loss if the crusted layer is 5, 10, and 15 cm deep. c. How does the value of part (a) change if the average crusted layer has a depth of 7.5cm?
