The textbook is designed to cover the second part of a standard thermodynamics course for mechanical, chemical, and electrical engineering students. The content is strictly organized around the application of the First and Second Laws of Thermodynamics to closed and open systems undergoing cyclic processes.
Engineering systems rarely deal with perfectly pure gases. This section introduces the physics of mixing multiple gases.
: The Reverse Brayton cycle, commonly applied in aircraft cooling systems. 3. Formulas and Key Mathematical Relations hipolito sta maria thermodynamics 2 pdf
Master the use of Steam Tables and Refrigerant Tables. Accurate interpolation of enthalpy ( ) and entropy ( ) is where most students win or lose points.
Sta. Maria demystifies the concept that refrigeration is essentially a heat engine running in reverse. The use of the Pressure-Enthalpy (P-h) diagram for refrigeration cycles is a core teaching tool in this section. The chapter on air conditioning introduces Psychrometrics, teaching students how to calculate specific humidity, relative humidity, and dew point—essential skills for HVAC design. The textbook is designed to cover the second
The textbook balances both unit systems, reflecting the dual standards often encountered by engineers in global industries.
Detailed analysis of the Otto Cycle (gasoline engines), Diesel Cycle , and the Dual Cycle . This section introduces the physics of mixing multiple gases
Detailed exploration of saturation temperature, subcooled and compressed liquids, and the use of steam tables for property determination.
