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:

  • Perform complete cycle analysis of: the internal combustion cycle; the steam power generation cycle; and of the refrigeration/heat pump cycle, being able to compare actual cycle performance to ideal cycle performance.
  • Specific Outcomes:
    • Define the following properties: specific volume, internal energy, enthalpy, entropy.
    • Locate compressed liquid, saturated liquid-vapor, superheated vapor states on the following plots: temperature-specific volume, pressure-specific volume, temperature-entropy, and pressure-enthalpy.
    • Evaluate properties of pure substances using thermodynamic tables.
    • Evaluate properties of ideal gasses using thermodynamic tables and ideal gas relations.
    • Evaluate properties of compressed liquids and ideal gasses using specific heats.
    • Apply the First Law of Thermodynamics to evaluate changes of state for closed and open systems. For example: rigid containers, piston-cylinder containers, nozzles, diffusers, turbines, compressors, expansion valves, mixing chambers, and heat exchangers.
    • Define entropy and describe its development from the Carnot cycle.
    • Apply the Second Law of Thermodynamics to evaluate the validity of a process and the ideal behavior/performance for closed and open systems.
    • Analyze turbine and compressor/pump efficiencies.
    • Identify the parameters that improve the performance of: internal combustion cycles, steam power generation cycles, and refrigeration/heat pump cycles.
    • Evaluate engineering thermodynamic cycles and their effect to the environment.
