I have a question, if i followed this set-up. Can i relate to processes of a real-life heat engine such as a stirling engine or which is the most suitable heat engine to relate it to.

I read about the mechanical efficiency of the heat engine in this article. I think that it is the ratio between Qh(work done by the gas) and Wout(work that the heat engine has done). Am i thinking in the right way? Also, what does thermal efficiency of a heat engine refer to? Thank you.

Hello, I'm confused between the difference between the thermal and mechanical efficiency of a Sterling heat engines or heat engines in general. I hope you could be able to guide and help me. Thank you

With regards to the first experimental set-up, so can i continue to with that set-up but just remove the spring and add a force meter, to detect the force by the expansion of the syringe, and does that force show the work done by the heat engine? If so, how can i calculate Qh of that set-up and...

thank you for the reply. It was v helpful for planning my experiment but i don’t understand why there will be water flow in and out in the experiment. On the other hand, is there any other ways or a simpler, lesser complicated model than this to learn about how the heat engine works, by using...

Yes, i tried this set-up before coming up with this. It didn’t seem to work because the syringe was a 100cc one and my school doesn’t have 10cc one which is suitable for this experiment. This didn’t make the air to expand in the syringe due it’s low pressure and it doesn’t have the power to lift...

Yes, i understand what you're trying to explain here. But the aim of my research is "What effect does the temperature difference between the hot source and the cold sink have on the mechanical efficiency of a heat engine?" and i just want to mainly to use this set-up to understand how a heat...

Thank you for your reply again. But is it possible that i can use this experimental set-up to calculate the mechanical efficiency of a heat engine. I think it is possible because i can calculate Qh, by using the formula for isothermal expansion and i can calculate Wext using the work done by...

Hello sir, Thank you for your reply. I have attached the diagram below. Hope you could help me with this.

but sir, i do not have a regenerator in the experimental setup. i just have a confusion to calculate the work done by the gas, but how does the pressure decrease after the isothermal expansion and increase after the isothermal compression. thank you

Please, i need help
