## Help with the Carnot Cycle

1. The problem statement, all variables and given/known data
its part VI) of a big problem, where:

0.12 moles of argon (40) undergoes the cycle abca described in the graph. Process ab lies on a 540k isotherm.

In the previious 5 sub problems, i figured that:

Tc=270k
Qbc=670J (lost)
Qca=400J (added)
Wab=370J
Wabca=100J

The PV diagram has points a,b and c where:

a=(1.5X10-3, 3.6X105)
b=(3X10-3, 1.8X105)
c=(1.5X10-3, 1.8X105)

2. Relevant equations

Q=mc$\Delta$T

$\Delta$U=Q+W

$\epsilon$=1-Qout/Qin=1-Tlow/Thigh

3. The attempt at a solution
So it's basically using Qabca to find the efficiecy. The thing is that im not sure what to use for the Qs.

 What is Qs supposed to represent? I don't see it in your problem statement.

it's a plural for Q, I am not sure what to use for Qin and Qout

## Help with the Carnot Cycle

Remember this is NOT a carnot cycle. η= 1- Qout/Qin There is also a Qin between A and B. Do you know what it is? It is the Qout/ the Total Qin.
