Suppose you had the choice of either raising the high-temperature reservoir a certain number of kelvins, or lowering the low-temperature reservoir the same number of kelvins. Which would you choose (assuming you wanted to increase the efficiency, of course)?
After doing experimenting with some random numbers, I thought the answer to be: lower the low-temperature reservoir.
For example,
1 - 100/300 = 66.7%
1 - 95/300 = 68.3%
1 - 100/305 = 67.2%
both of the last two are greater than the first, but the second has the greatest efficiency.
However, my book says to raise the high-temperature reservoir. Is my book wrong?
