I don't know, how many guesses do we get.
Providing a bit more information and perhaps a short introduction of yourself might improve the chance of a sensible answer.Brian - Newton Abbot, Devon, UK

Obviously, whoever wrote the question had an answer in mind and it would be a good question if more information was presented.If all else fails, ask for help.

My point with my first answer.
It is assumed by one and all that he is asking about a cooling water system but we still don't know for sure.Brian - Newton Abbot, Devon, UK

Re: Exam Question
You are right Brian. I made the assumption he was talking about a water-cooled system. It might very well be an air-cooled condenser with a water spray on it for we know right now.
If all else fails, ask for help.

Re: Exam Question
any temp above normal would indicate scale formation yes? seems like a trick question, ie if normaly you see temp x then you see temp x + 3f then youve got something reducing your heat transfer (assumiong everthing else is equal) which could be scale and seeing as the question asks about scale then......
it must be B!
