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
That sounds right, but your source should include the definition if it is introducing the term.Poorneshwar 2 said: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?
I would think thermal means thermodynamic, but it is possible they are also referring to a real-world, non-ideal process. But again, the text you are reading it from should define it.Also, what does thermal efficiency of a heat engine refer to?
Thermal efficiency refers to the ratio of the amount of heat energy produced by a system to the amount of fuel energy consumed. Mechanical efficiency, on the other hand, refers to the ratio of the amount of useful work output to the amount of work input.
Thermal efficiency is calculated by dividing the heat energy produced by the fuel energy consumed, multiplied by 100%. Mechanical efficiency is calculated by dividing the useful work output by the work input, multiplied by 100%.
Thermal efficiency can be affected by factors such as the type of fuel used, the design of the system, and the operating conditions. Mechanical efficiency can be affected by factors such as friction, wear and tear, and the design of the system.
Both thermal and mechanical efficiency are important in their own ways. Thermal efficiency is important for maximizing the use of fuel and reducing waste, while mechanical efficiency is important for ensuring that the system is working effectively and producing the desired output.
Thermal efficiency can be improved by using more efficient fuels, optimizing the design of the system, and maintaining proper operating conditions. Mechanical efficiency can be improved by reducing friction and wear, optimizing the design of the system, and performing regular maintenance and repairs.
