A. and Boles, M. A., Thermodynamics: an Engineering Approach, 6th ed., The McGraw-Hill Companies, New York.</p><p>Course Objectives: The students will be asked to demonstrate their knowledge of the material covered in Thermodynamics II through their mastery of the following course objectives. Through the study of Thermodynamics II the student will be able to: </p><p>1. Analyze ideal gas and steam power cycles and refrigeration cycles to determine system components and process diagrams, perform energy balances, determine heat and work transfers, calculate the cycle efficiency or coefficient of performance and design power/refrigeration cycles or processes for cycle components; 2. Calculate properties of ideal gas mixtures and determine the properties of dry air-water vapor mixtures, plot processes on a psychrometric chart, and analyze process involving dry air-water vapor mixtures to perform energy and mass balances for the processes; 3. Determine balanced chemical reaction equations and analyze typical combustion processes to perform energy balances to determine the heat transfer released or estimate the maximum possible product gas temperature during combustion and use the results of chemical equilibrium analysis to write balanced chemical reaction equations and to perform energy balances for reaction systems; 4. Calculate stagnation properties of high-speed flows and apply these properties for one- dimensional, compressible flow to isentropic flow though nozzles and to the process occurring across a normal shock wave.</p><p>Topics covered: (number of classes): Based on 3 classes (+ 1 hr tutorial) per week:</p><p>1.
