(adsbygoogle = window.adsbygoogle || []).push({}); 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:

T_{c}=270k

Q_{bc}=670J (lost)

Q_{ca}=400J (added)

W_{ab}=370J

W_{abca}=100J

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

a=(1.5X10^{-3}, 3.6X10^{5})

b=(3X10^{-3}, 1.8X10^{5})

c=(1.5X10^{-3}, 1.8X10^{5})

2. Relevant equations

Q=mc[itex]\Delta[/itex]T

[itex]\Delta[/itex]U=Q+W

[itex]\epsilon[/itex]=1-Q_{out}/Q_{in}=1-T_{low}/T_{high}

3. The attempt at a solution

So it's basically using Q_{abca}to find the efficiecy. The thing is that im not sure what to use for the Qs.
