In the United States, electricity is sold using the SI units of kilowatt (kW) or megawatt (MW), and fuel for power generation stations is generally purchased using English units, e.g., British thermal unit (Btu), gallon (gal), and ton. An industrial power plant has an average annual load of 100 MW (electrical). If the overall thermal efficiency is 33% (based on HHV), what is the annual cost of fuel if the plant is fired with (a) natural gas, (b) No. 2 fuel oil, and (c) bituminous coal? Use the data from Tables 2.2, 2.7, and 2.13. Assume the cost of natural gas is $5/million Btu, the cost of No. 2 fuel oil is $3/gal, and the cost of bituminous coal is $60/ton (1 ton = 2000 lbm)
Completely solve and box the final answer. Please show the units to show the unit cancellations. Write legibly 2. During a steady flow process, the pressure of the working substance drops from 1,380 kpa to 138 kpa, the speed increases from 61 m/s to 305 m/s, the internal energy of the open system decreases 58.1 KJ/kg, and the specific volume increases from 0.0625 m3/kg to 0.5 m3/kg. No heat is transferred, determine the work in KW if the mass flow at the rate of 272.15 kg/hr.
In the movie Back to the Future, Marty travels back in time to 1955. In 1955, the only available light bulbs in the United States were incandescent bulbs. Assume that last year, you traveled back in time to 1955 and changed all the light bulbs in a single average American household (45 light bulbs) from 75-watt incandescent bulbs to the corresponding 17-watt LED bulbs. The estimated usage is 3 hours per day , at a cost of $0.11 per kilowatt-hour . Based on energy cost alone - not considering the cost to replace any light bulbs and not considering any changes in energy cost with time - how much money in dollars would this household have saved over a 66-year time span (from 1955 to 2021) by changing from incandescent to LED bulbs?
Seawater can be purified by distillation into potable water. If it costs 15 cents per kilowatt-hour for energy, what is the cost of energy to produce 100.0 gallons of drinking water at 100.0 ˚C if the seawater starts at 25.00 ˚C? (1 watt × 1 second = 1 joule). Enter your answer to the nearest penny.

Suppose you're converting a bill of materials for machining feedstock from the British gravitational (U.S. system) of units to International System (SI) units. Your goal is to have all of the material quantities in kilograms. Your bill of materials lists values for required weights of brass rod in pounds. To convert to these values to kilograms you first you divide by gravitational acceleration in feet per second squared to get a mass in slugs, then convert slugs to kilograms using standard conversion factors. Group of answer choices True False
