better in MAE 301 1 3 Designation of course as a General Education Requirement GER N A 1 4 Student learning outcomes for the course Course Motivation This course places emphasis on the analysis and design of power and refrigeration cycles and the application of the basic principles to engineering design problems with systems involving mixtures of ideal gases psychrometrics nonideal gases chemical reactions combustion chemical equilibrium and one dimensional compressible flow Course Objectives The students will be asked to demonstrate their knowledge of the material covered in MAE 302 through their mastery of the following course objectives Through the study of MAE 302 the student will be able to Sketch figures of systems and control volumes Sketch process diagrams for the processes occurring within systems and control volumes Develop the governing equations for conservation of mass conservation of energy and process relations for processes occurring in systems and control volumes Determine the required thermodynamic properties from tables for real substances water and refrigerant 134a tables for ideal gases and equations of state for ideal gases substitute these property values with units into the governing equations and simplify Analyze ideal gas power cycles to perform energy balances determine heat and work transfers and calculate the cycle efficiency Analyze steam power cycles to perform energy balances determine heat and work transfers and calculate the cycle efficiency Analyze vapor compression refrigeration cycles to perform energy balances determine heat and work transfers and calculate the cycle coefficient of performance Page 1 of 6 MAE 302 Summer 2015 Calculate properties of ideal gas mixtures 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 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 Calculate stagnation properties of high speed flows and apply these properties to isentropic flow though nozzles and to the process occurring across a normal shock wave 1 5 All required
