# ENGR& 224Thermodynamics• 4 Cr.

## Description:

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.

## Outcomes:

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.
