Résumé	The Thermal Resistance Network method uses electrical circuit analogy to solve heat transfer problems. It treats heat flow as analogous to electric current, thermal resistance analogous to electrical resistance, and temperature difference analogous to voltage potential. This powerful conceptual framework enables engineers to analyze complex multi-layer heat transfer systems systematically.	The Log Mean Temperature Difference (LMTD) method is a fundamental tool for calculating heat transfer rates in heat exchangers. It defines the effective temperature difference between two fluids as the logarithmic average of the temperature differences at the inlet and outlet. This method enables engineers to size and analyze heat exchangers systematically using the basic heat transfer equation Q = U A LMTD.
