Your company would like to build a plant that produces 200 kMTA of fuel-grade ethanol from corn using a dry-milling process. The overall yield is 2.5 gallons of ethanol per bushel of corn. A byproduct of the process is livestock feed produced at 22 pounds per bushel of corn (the livestock feed is valued at $0.05/lb). Assuming the total operating costs for the plant will be $20MM per year, determine the simple payback time and the simple pre-tax return on investment for building the plant.

Amass of 1.5 kg of air at 120 kpa and 24Β°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
