I am sorry I am not as technically inclined as you. Can you please explain to me how characterize the reactor with 2 thermometers, barometers, and beaker?
Again I apologize. I have only spent the last 40 years designing, testing and operating power plants. Maybe I missed something.
There is actually a book titled “Fermi’s Solution.” Read it.
There is a cartoon with the caption (more or less): “On the Internet, no one knows if you are a dog.”
Saying you have 40 yrs experience in engineering means nothing. If you know your stuff, you can talk “turkey”.
Go home and do the homework. Laziness is not tolerated.
