For countless engineering students, particularly in mechanical and chemical engineering programs, Hipólito Sta. Maria’s Thermodynamics textbook remains a cornerstone. Its systematic problem-solving approach, clear derivations, and chapter-end exercises make it invaluable. Among all chapters, stands out as a conceptual and computational hurdle. This chapter typically covers the Second Law of Thermodynamics , entropy , reversibility , irreversibility , and related cycles.

From entropy balance (control volume, steady, adiabatic, 1-in 1-out): [ s_2a - s_1 = s_gen \quad (\textsince \dotQ=0, \dotm=1) ] Thus (s_gen = s_2a - s_1) in kJ/kg·K. Must be > 0. Maria appear on these platforms
This matches the Second Law: reversible → total entropy change zero.
