1. The problem statement, all variables and given/known data
2. Relevant equations
3. The attempt at a solution
I am confused as to which streams I should use for the log mean temperature difference. I am pretty sure it should be the difference in temperature between the two streams on the same side, so I think it's
(700450)(1100960) / ln [(700450)/(1100960)], but I am not sure.
The term wasn't well defined, and my search on wikipedia gave the definition as ''The LMTD is a logarithmic average of the temperature difference between the hot and cold streams at each end of the exchanger.''
This is too vague, which end of the exchanger??
