Összefoglaló	The Lumped Capacitance Method is a simplification technique for solving unsteady-state heat transfer problems. It assumes that thermal properties are uniform throughout a solid body and that temperature variations within the object are negligible. This approach enables engineers to solve complex transient heat conduction problems using ordinary differential equations rather than partial differential equations.	The Effectiveness-NTU method is an alternative approach to heat exchanger analysis that measures thermal performance relative to the theoretical maximum possible heat transfer. It is particularly powerful for design problems where outlet temperatures are unknown. The method uses effectiveness (ratio of actual to maximum possible heat transfer) and NTU (Number of Transfer Units, a dimensionless parameter related to overall heat transfer area) to characterize heat exchanger performance.
