Prince George's Community College:EGR 2060:Thermodynamics
Principles of macroscopic thermodynamics, focusing on mass transport and energy, heat and work, the properties of pure substances and mixtures, the first and second laws, and reversible cycles.
This course extends the thermodynamic properties found in chemistry courses. These concepts universally are those in the ideal gas region which are then completed going from the ideal gas region, to the saturated region, the superheated region, and the compressed liquid region.
The course is approached from the engineering point of view (as opposed to a physics point of view), making extensive use of thermodynamic tables. Many of the systems analyzed evolve from one region into another (saturated to super heated, etc,). This course prepares the student for the more complex courses in higher-level civil, mechanical, and aerospace engineering courses.
Students will become familiar with the several methods of analyzing various systems undergoing heat transfer processes. Student will be able to analyze systems using the proper mathematical tools and physical laws such as The First Law of Thermodynamics, The First Law for Control Volumes, The Second Law of Thermodynamics and The Second Law for Control Volumes.
All problems require university-level reading skills, the ability to abstract, analyze systems mathematically, and graphically. Introduces the foundations of the chemistry and physics of materials used in engineering applications.
