ENGR& 224 Thermodynamics • 4 Cr.


Introduces basic principles of thermodynamics from a predominately macroscopic point of view. Topics include the basic laws of thermodynamics as relating to energy transformations and state changes in engineering problems. Recommended: CHEM& 162 and MATH& 152.


After completing this class, students should be able to:

  • Define the thermodynamic properties of: mass, volume, pressure, temperature.
  • Evaluate pure substance thermodynamic properties of: specific volume, internal energy, enthalpy, entropy.
  • Identify and describe pure substance behavior in various states: solid, liquid, gases and state transitions.
  • Apply the First Law of Thermodynamics to evaluate closed and open systems such as: rigid containers, piston-cylinder containers, nozzles, diffusers, turbines, compressors, expansion valves, mixing chambers and heat exchangers.
  • Apply the Second Law of Thermodynamics to evaluate the validity of a process and the ideal behavior/performance for closed and open systems.
  • Perform analysis of the steam power generation cycle and of the refrigeration/heat pump cycle.
