Answering your question: the point of the question is not why the heat transfer is interrupted at a given temperature. There are several control mechanisms to make the convection coefficient zero or virtually zero, especially if there is forced ventilation. |
Don't take my post personally .. I was criticising the overuse of equations when dealing with problems ... the average physics student when he finishes education , soon forgets equations , and has not developed logic and common sense and is soon unable to solve the simplest thing .
I wasn't referring to anyone here as "the average person" , but the public in general...
The question says " the water tank stops transmitting heat to the system when the temperature reaches 300K. " (the system temp is 293K) this does not make sense ..and will effect all calculations relating to this problem.
I suggest the question has not been given correctly.
But your post did make me smile , you give 7 lines of formulas , then say "Now I think you can solve the questions"!!!
I ask kiris91 ...has that helped you solve the questions??
