Let’s look at the Energy conversions in a power plant. Please watch the following 6:09 video:
Now view a demonstration of a small-scale power plant in the 7:01 video below:
The basic energy conversions in the three main components in a power plant are shown quantitatively in the 4:26 video below:
Below are two temperature scales. The first scale, labeled "HOT," shows the range of temperatures for the combustion of gases in a power plant. The second scale, labeled "COLD," shows the range of temperatures at which gases are exhausted from the power plant.
Instructions: Select numbers from the range on the "HOT" scale and enter them (one at a time) into the text box labeled "HOT" below. At the same time, select numbers from the range on the "COLD" scale and enter them (one at a time) into the text box labeled "COLD" below. Try various combinations of hot and cold numbers and observe the graph to see the temperatures' effect on efficiency.
