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?
