SUMMARY

This discussion focuses on the processes involved in a steam engine, specifically identifying the isochoric, isothermal, isobaric, and adiabatic processes. Participants clarify that the isochoric process occurs within the cylinder during compression when the piston moves inward. The conversation emphasizes the importance of understanding thermodynamics through dedicated study, recommending resources like physics textbooks and websites such as physicsclassroom.com and hyperphysics.com for foundational knowledge.

PREREQUISITES
  • Understanding of basic thermodynamic processes: isochoric, isothermal, isobaric, and adiabatic.
  • Familiarity with steam engine mechanics and operation.
  • Knowledge of pressure-volume diagrams and their interpretation.
  • Basic physics concepts related to heat transfer and energy conservation.
NEXT STEPS
  • Read a chapter on thermodynamics in a physics textbook.
  • Explore the thermodynamics section on physicsclassroom.com.
  • Investigate the concepts of pressure-volume work in steam engines.
  • Study the differences between isochoric and isothermal processes in detail.
USEFUL FOR

Students studying thermodynamics, engineers working with steam engines, and anyone seeking to deepen their understanding of thermal processes in mechanical systems.

Can someone explain to me which different processes there are in this steam engine? And where they start and end? I can't find figure it out...

Is this homework? The processes are labeled on the diagram...could you be more specific about what you don't understand?
 
What a bizarrely interesting diagram. It's a schematic and a graph intergrated in one illo.
 
The problem is, I don't know where the exact process is happening, fx. I don't know where the isochore proces is on the diagram or if there is a isochore proces at all
 
There are four different processes, isocore, isoterm, isobar and a adiabatic process.

Well. . The exact process is happening in the Cylinder. If the Piston press in that's the compression comes in. and i think the process is Isochore.
 
You should not expect PF helpful staff to explain thermodynamics to you, you should
1.read a chapter on thermodynamics in a physics books
2. read the section on thermodynamics at physicsclassroom.com or hyperphysics.com , both are great sites
3. if you have any questions about thermal dynamics please ask them here after you have done some research on it.
But basically it has to do with differences in potential, Hot Air goes to wear cool air is.
