The input heat of a Carnot engine is 3,000 J. The temperature of a hot reservoir is 600 K and that of a cold reservoir is 300 K. What is the work done? Hint: The efficiency e of a Carnot engine is defined as the ratio of the work done, W, by the engine to the input heat QH : e=W/QH. W=QH – QC, where Qc is the output heat. That is, e=1-Qc/QH =1-Tc/TH, where Tc for a temperature of...
Part A
For each engine calculate ?E
= QH?Wout?QC, where
QH is the amount of heat transferred from the hot
reservoir, QC is the amount of heat transferred to the
cold reservoir, Wout is the energy output of the heat
engine. QH, Wout, QC are positive
quantities.
?E(a), ?E(b), ?E(c) =
Part B
For each engine calculate the theoretical maximum efficiency
(Carnot efficiency) emax.
emax,(a), emax,(b), emax,(c) =
Part C
For each engine calculate the actual efficiency e.

A reversible heat engine operates between a high temperature reservoir at Th and a low temperature reservoir at Tư. The work produced by the heat engine is used to drive a reversible refrigerator that operates between the same two reservoirs. Determine if the low temperature reservoir is being cooled or heated.

Learning Goal:
To understand what a heat engine is and its theoretical
limitations.
Ever since Hero demonstrated a crude steam turbine in ancient
Greece, humans have dreamed of converting heat into work. If a fire
can boil a pot and make the lid jump up and down, why can't heat be
made to do useful work?
A heat engine is a device designed to convert heat into work.
The heat engines we will study will be cyclic: The working
substance...
