How Is Net Work Calculated in a Thermodynamic Cycle?
Click For Summary
Homework Help Overview
The discussion revolves around calculating net work in a thermodynamic cycle, specifically focusing on the work done during different segments of the cycle and the relationship between heat and work in thermodynamics.
Discussion Character
- Exploratory, Assumption checking
Approaches and Questions Raised
- Participants discuss the calculation of net work by considering the individual works done in different segments of the cycle. There is a question about whether the works can simply be added together. Some participants also express confusion about the signs of the work values based on the nature of the processes (expansion vs. compression).
Discussion Status
The discussion is ongoing, with participants raising questions about the calculation methods and the visibility of attachments. Some guidance has been provided regarding the approval process for attachments, but there is no clear consensus on the calculation of net work.
Contextual Notes
There are mentions of attachments that require moderator approval, which may be relevant to the discussion. Additionally, there is a focus on the signs of work related to the processes in the thermodynamic cycle.

Because they have to be approved by a moderator. We've had people attach porn in the past, so every attachment goes through a moderation queue. I've just approved all your attachments.
Are you sure about that? ab is an expansion, while ca is a compression. [itex]\int p dV[/itex] has a different sign along each path.
