Use ɛ-NTU, since temperatures are given find heat exchanger effectiveness with help of heat capacity rates.

Khaled Hossin

Dear Vishwam Shah,

Both methods can be used in the analysis of the heat exchangers. E-NTU can easily be used and has the advantage when only the inlet temperatures are known, however, the LMTD is recommended when all the terminal temperatures are known.

All the best

Vishwam Shah

Hello

Thank you Shazia Farman Ali and Khaled Hossin for the response. The informations will be greatly helpful
