Petroleum savings via ethanol use: The production of ethanol for use in liquid fuels has beenheavily subsidized in recent years. In assessing the success of these programs, it's important to keep the entire life cycle of ethanol fuels in mind.
a. Up to 10% by volume of gasoline in theU.S. may consist of corn-based ethanol. Using this information, calculate the amount of crude oilthat the U.S. saves per year via the displacement of gasoline by ethanol.
b. Burning of ethanol isalso more favorable than burning of gasoline from a carbon-emissions standpoint. Calculate thetonnage of CO2 saved per year by displacement of gasoline with ethanol in the U.S.
c. Find theamount of oil consumed in the conversion of corn to ethanol. Compare this to the amountconsumed during the oil refining process which supplies us with gasoline
d. What factors havebeen left out of this calculation so far?
Find references for the magnitudes of these factors, andsum up the total amount of petroleum saved in a year, and total amount of CO2 saved in a year
Take the saturation temperature of n-propanol at 2.1 bar as 118oC. The otherphysical properties required can be found in the literature, or estimated.
Determine the relationship between flow rate and temperature of the water fed to the scrubber. Is the rate at which heat must be removed from the water as it is pumped 5. If all of the sulfur in the coal reacts to form H2S, determine the air requi..
The labor force is 100 million and the unemployment rate is 5 percent. One million people quit looking for a job. What is it called when an individual leaves the labor force, and in this case what is the new unemployment rate?
The ship must unload 1000 metric tons within 5 hours to avoid demurrage charges. Estimate the power required by the pump. Take the pump efficiency as 70%. Physical properties of toluene: density 874 kg/m3, viscosity 0.62 mNm-2 s.
Three identical impedances of 30 ∠30° Ω are connected in delta to a three-phase 173-V system by conductors that have impedances of 0.8 + j0.6 Ω each. Compute the magnitude of the line-to-line voltage at the terminals of the load.
Consider an ordinary, helium-filled party balloon with a volume of 2.2ft3 . The lifting force on the balloon due to the outside air is the net resultant of the pressure distribution exerted on the exterior surface of the balloon.
Use molecular orbital theory to predict whether the bond order in the superoxide ion, O2-, should be higher or lower than the bond order in neutral O2 molecule.Is the bond order of O2- higer or lower than that of O2?
