Question
Calculate the efficiency of the Carnot Engine for ideal gas. Consider the figure below for a complete cycle of Carnot engine, where the cycle goes from ad -> ab -> bc -> cd.
Where the 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 are TC and _______.
Sol.
Since deltaU = 0, then the heat segment ab is
QH = _____TH ln |_____/______|
The heat segment on cd is
QC = -_____TC ln |_____/_____|
By inspection, we can say that
THVYb-1 = _______VYc-1
and
TH_______Y-1 = _______VYd-1
Thus,
Vb/_______ - _______/_______
Then,
|QC-QH| = |_______/_______|
which solves the efficiency of the carnot engine.
