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.

Thus, Vb/ = then |QC/QH| = | %3D Which solves the efficiency of the Carnot engine.
