The maximum metal temperature is that of the highest temperature of the hot-side fluid entering it.

There are a number of mean temperature calculations, depending on the application to which the calculation is put. Normally, the log-mean temperature difference is used to size the area of the exchanger, for example.

Google "LMTD" or "Log Mean Temperature Difference"?
