Homework Statement
There is a heat engine with Th on top at 100 J pointing down, Tc on bottom pointing down with 50 J and the work output is 50 J pointing right out of the engine. (ENGINE 1)
a) Draw the diagram for a carnot refrigerator which draws 100 J of heat from the hot reservoir (Th = 450 K and Tc = 270 K). we have to find the work output and the heat dumped to the cold reservoir. Using this information, make a new heat engine. (ENGINE 2)
b) what is the engine that results when you combine the two engines. (#1 and 2)
c) what is interesting about this combination?
Homework Equations
efficiency = 1 - QL/QH
ideal efficiency = 1 - TL/TH
The Attempt at a Solution
A carnot engine is basically one in which everything is perfect. This can never exist in reality. In the refrigerator heat engine, the arrow for TH should point up, the arrow for TL(TC) should point up and the energy should point in. However, I am not able to figure out the values for them besides the fact that TH is 100 J since that is given. Without this information, I can't do part B and C
