Concept explainers

Total Energy Consumption

The term energy consumption signifies the consumption of electricity. Energy consumption as electricity is a primary demand for households, factories, industries, complexes, and commercial places. According to a report, the total U.S. energy consumption for 2018 was 101 BTU (British Thermal Units). It accounted for 17% of the total energy consumption of the world. The total energy demand for the U.S. as oil equivalent was estimated to be about 6804 kg of oil equivalent.

Henry Ford’s Model T was originally designed and built to run on ethanol. Today, ethanol (190-proof alcohol) can be produced with domestic stills for about $0.85 per gallon. When blended with gasoline costing $4.15 per gallon, a 20% ethanol and 80% gasoline mixture costs $3.28 per gallon. Assume fuel consumption at 25 mpg and engine performance in general are not adversely affected with this 20–80 blend (called E20). How much money can be saved for 15,000 miles of driving per year?
A paint shop buys 52,000 liters of car paint based on VOC. In one year, they applied 50,800 liters of same paint onto the products and the remainder turned out to become a waste. Assuming the waste disposed in an air-tight container and none accumulates in the shop or anywhere else, a. Determine the mass of VOCs entered into the atmosphere (in kg/year) if the density of paint is 8.30 lb/gallon and 75% by weight of VOCs are present in the paint. b. It was later found that the air-tight waste container had a leak. What will be the maximum mass of VOCs would have entered into the atmosphere in the same year?
Each month the Speedy Dry Cleaning Company buys 1 barrel (0.160 m3) of dry cleaning fluid. Ninety percent of the fluid is lost to the atmosphere and 10 percent remains as residue to be disposed of. The density of the dry cleaning fluid is 1.5940 g/mL. Draw a mass balance diagram and estimate the monthly mass emission rate to the atmosphere in kg/mo
The default carbon dioxide emission factor for biodiesel fuel is 70,800 kg/TJ, and the emission factor for diesel fuel is 74,100 kg/TJ. Which diesel fuel, biodiesel or “regular” diesel fuel, has the greater carbon intensity per unit of energy? What are their respective carbon intensities compared to natural gas? If a city were to invest in climate-friendly buses for public transportation, should it choose a diesel-powered bus, a biodiesel-powered bus, or a natural gas-powered bus?
A 20,000 L tank of water with pH of 7.5 is to be treated with a liquid hydrogen bromide acid (HBr). If after 5000 L of the acid was added to the volume in the tank the pH becomes 5.5, how much mass of hydrogen was added to the system? How much total HBr was added?
It has been suggested that carbon dioxide emissions should be taxed at $30 per metric ton (106 g C). Removal of CO2 from the atmosphere would be worth the same amount.

Calculate the value of all the CO2 in Earth’s atmosphere? [Hints: The total atmospheric mass is 5.1480×1018 kg and it is composed of 80% N2 and 20% O2.

Pilot plant studies of the adsorption process indicate that 11 lb (net) of ethylbenzene will be adsorbed per 100 lb of carbon during normal everyday operations. Calculate the minimum amount of carbon needed m one bed for a two-hour run time. Give your answer In pounds.
A family consists of an adult male weighing 70 kg, an adult female weighing 50 kg, and a child weighing 15 kg. The air they breathe contains 1 µg/m3 of a listed carcinogenic chemical, and the waste they drink contains 1 µg/L of the same chemical. Assume the air intake for adult and child is 20 m3 /day and water intake for adult and child is 2 L/day. The body retains 80% of the air pollutant and 100% of the water pollutant. Estimate the total chemical dose per kg of body weight for each family member per day correctly.
