Carnot Cycle question

  1. Feb 17, 2008 #1
    1. The problem statement, all variables and given/known data



    2. Relevant equations
    You are designing a steam engine and you want to make it as efficient as
    possible in terms of the energy used to run it and the useful energy it can
    produce. What do you want to maximize and minimize in terms of the
    steam temperature and the exhaust temperature? (hint: Think Carnot Cycle)


    3. The attempt at a solution

    Maximize steam temperature / minimize exhaust temperature?

    Suggestion : look more into detail at the different steps of a Carnot Cycle. Then, try to recognize these stadia in your steam engine. Finally, figure out why the Carnot cycle is "so efficient" and apply this knowledge onto your example here.

    This is the way you should proceed. So, in your next post, you will have written the different stages of the Carnot cycle and you will have linked them to your steam engine. Then you will know what this engine actually is supposed to do and which process needs to be adapted to optimize the device.
