Question
1. Consider the informational postcard and simulated fuel pellet provided by the nuclear company BWXT, shown below: NUCLEAR. CLEAN AIR ENERGY. 149 GALLONS OF OIL America's 104 nuclear energy reactors provide emission-free electricity for one in five homes and businesses. The uranium fuel they use is so efficient that just fuel pellet provides as much energy as: ONE TON OF COAL Five uranium fuel pellets meet a household's electricty needs for a year 17,000 CUBIC FEET OF NATURAL GAS a) According to this information, what is the energy content of a single uranium fuel pellet, in joules? [1 pt] b) According to this information, how much electricity does a household use in one year, in KWh? [l pt] Using information on course handouts, calculate the energy content of 149 gallons of oil, one ton of coal, and 17.000 f3 of natural gas. Do your calculations agree with the numbers provided? 12 pts] c) d) Comment qualitatively on this display of information, including the written comments as well as the images/photos used. Do you think that this is a good infographic? Why or why not? 12 pts]Explanation / Answer
a) According to this information, the energy content of a single uranium fuel pellet is same energy produced by buring 1 ton of coal, by buring 149 gallons of oil or by buring 17,000 feet cube of natural gas, which is equivalent to 21-22 gigajoule
b) According to this information, the 23333.34KWh - 24444.45KWh hour of electricity a household use in one year
c)1ton of coal = 21-22gigajoules of energy
149 gallon of oil = 18gigajoules (approx) of energy
16,000 cubic feet of natural gas = 17.94 gigajoule of energy
As per the unit conversion given above, these value not exactly closed to each other, there is a variation of 4units , but one could approximately consider them close to each other
d) this is not a good infographic because value used here are approximately equal to each other, but scientific units conversion are also considered when they are exactly, approximation can proved good for economic use but not for scientific purposes
