Acorn ethanol production plant receives 500,000.0 kg/day corn feedstock at a moisture content of 15.5% (wet basis). if all of this corn is converted into ethanol what is the theoretical volume of ethanol that this facility can produce per day? assume that the starch content of corn grain is 68.5%. the density of ethanol is 789 kg/m3. answer in us gallons/day with at least 3 sig figs.

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
