WebThe First Law of Thermodynamics. The first law of thermodynamics thinks big: it deals with the total amount of energy in the universe, and in particular, it states that this total amount does not change. Put another way, the First Law of Thermodynamics states that energy … WebSep 13, 2024 · The results were determined experimentally in terms of first law and second law efficiency, maximum temperature difference, and overall heat transfer coefficient over a 48 hours cooling period. The porous media thickness was used as a parameter and its values were chosen as 10, 12, 14, and 16 cm.
