ES 204 - Thermodynamics
Credit Hours: 4
This course covers first and second laws of thermodynamics, thermodynamic properties, equilibrium and their application to physical and chemical systems.
At the conclusion of this course, the student should be able to:
- determine properties of real substances, such as steam and refrigerant 134-a, and ideal gases from either tabular data or equations of state;
- use absolute, gage, and vacuum pressures correctly;
- calculate gage and vacuum pressures using the manometer equation;
- use absolute and Celsius temperatures correctly;
- determine property data using the steam and R-134a tables;
- sketch P-v, T-v, and P-T plots for steam, R-134a, and ideal gases;
- locate data states on P-v, T-v, and P-T plots for steam, R-134a, and ideal gases;
- determine the condition of a data state as a compressed, saturated, or superheated state and determine the thermodynamic properties at that state by using property tables;
- demonstrate the use of quality in finding properties of two-phase substances;
- apply the concept of the generalized compressibility factor to demonstrate when the ideal gas equation may be used to determine the state of a gas;
- apply the ideal gas equation to solve problems involving pressure, temperature, and volume of ideal gases;
- determine changes in internal energy and enthalpy for ideal gases; and
- determine mass flow rate from its definition and relation to volume flow rate.
- analyze processes involving ideal gases and real substances as working fluids in both closed systems and open systems or control volumes to determine process diagrams, apply the first law of thermodynamics to perform energy balances, and determine heat and work transfers;
- determine the pressure-volume relation for processes and plot the processes on P-v and diagrams;
- calculate the boundary work for a variety of processes for closed systems;
- apply the first law to closed systems containing ideal gases, steam, or R-134a to determine heat transfer, work, or property changes during processes; and
- apply the first law to steady-flow open systems containing ideal gases, steam, and refrigerant-134a to determine heat transfer, work, and property changes during processes.
- analyze systems and control volumes through the application of the second law; and
- determine the efficiency of heat engines and compare with the Carnot heat engine efficiency;
- determine the coefficient of performance of refrigerators and heat pumps and compare with refrigerators and heat pumps operating on the reversed Carnot cycle;
- determine entropy changes for both ideal gases and real substances;
- determine the properties of a working fluid at the end of an isentropic process;
- plot processes on both P-v and T-s diagrams; and
- apply both the first and second laws to determine heat transfer, work, and property changes during processes occurring in both closed and open systems.
- analyze systems through the application of the concepts of energy.
