Course DescriptionCovers application of principles of thermodynamics in the analysis of vapor and gas power cycles, refrigeration and heat pump machinery, and air distribution systems. Combustion reactions, ideal gas mixtures, and properties of moist air (psychrometrics) are also studied. Prerequisites: CMET 212. Audit available.
Intended Outcomes for the course
Upon successful completion of this course, the student will be able to:
- Apply the first and second laws of thermodynamics in the analysis of:
- Rankine and Brayton power cycles
- Refrigeration machinery
- Heat pump systems
- Evaluate energy consumption and/or production a various thermal systems.
- Determine the efficiency of thermodynamic cycles.
- Identify cycle components and describe their function.
- Draw cycle and temperature-enthalpy diagrams.
- Discuss the appropriateness of using different types of refrigerants and working fluids in various applications.
- Use a psychrometric chart to determine properties of moist air.
- Predict products of combustion processes using stoichiometric analysis.
- Use the fan laws to analyze and size air distribution systems.
Outcome Assessment Strategies
Student progress will be measured by performance on homework and on objective mid-term examinations covering appropriate types of problems. A comprehensive final exam will also be administered.
