Thermodynamics is notorious for complex math. Sta. Maria simplifies this by providing explicit, sequential solution paths for every sample problem.

Introduction to Psychrometrics, involving air-conditioning processes and cooling towers. Why It Is Popular

: Comprising isentropic compression, constant-pressure heat addition, isentropic expansion, and constant-pressure heat rejection.

Hipólito Sta. Maria passed away in the early 2010s, but his books remain in use. In 2022, a revised edition was supposedly in the works, but many students still cling to the old PDF—not just for cost, but because the problems and solutions in that specific edition align perfectly with decades of board exam questions.

Sta. Maria’s textbooks are renowned for being perfectly aligned with the Mechanical Engineering curriculum in the Philippines. This makes them essential for both academic success and licensure exam preparation.

Thermodynamics is a cornerstone of mechanical, chemical, and aerospace engineering. While introductory courses focus on basic laws and properties, advanced applications require a deeper dive into power cycles, refrigeration, and gas mixtures. For engineering students in the Philippines and worldwide, is one of the most reliable and widely used textbooks to master these complex topics.

The end-of-chapter problems are infamous, but solving them is the best way to prepare for exams. Conclusion

An introduction to the thermodynamics of reacting systems, focusing on air-fuel ratios, enthalpy of formation, and finding the efficiency of combustion chambers.

Searching platforms like Lazada or Shopee for physical copies is often a better investment for long-term use.

: Examination of internal combustion engine cycles, including Otto , Diesel , and Dual cycles.

| Chapter(s) | Topic | | :--- | :--- | | | Development of the first law of thermodynamics and energy analysis of open systems. | | 3 & 4 | Presentation of the equation of state and processes involving ideal gases. | | 5 & 6 | The second law of thermodynamics and its applications to different thermodynamic cycles. | | 7 | Gas compressors and their operations. | | 8 | The Brayton cycle. |

: The standard ideal cycle for vapor power plants.

If you get stuck, use the solution manual to find the exact step where you failed (e.g., a wrong property lookup, an algebraic error, or an incorrect boundary assumption).

The textbook is structurally divided into several critical chapters, each focusing on a specific engineering application of thermodynamic principles. Steam Power Plant Cycles
