Question
Where segments ad & bc are the
processes and segment ab & cd are the
processes; and the volumes involved are Va, Vb, Vc, Vd, and the two temperatures
TC and
Sol.
Since AU = 0, then the heat on segment ab is
%3D
QH =
TH I |
The heat on segment cd is
QC = -
TC In |
By inspection, we can say that
VY-1
and
TH
Y-1_
d
Thus,
Vb/
then
TQC/QH| = |
Which solves the efficiency of the Carnot engine.
