A course for senior mechanical engineering students. The subject matter consists of a study of modern practice in steam power plants and heating and ventilation systems. Boilers, feedwater heaters, condensers and other plant auxiliaries are studied. The economics of power generation is discussed. Individual problems are assigned on power plants design and on heating and ventilation systems. _Text: Barnard, Ellenwood, Hirshfeld, “Heat Power Engineering”, Vol. 2, 3; Severns, “Heating, Ventilation and Air Conditioning Fundamentals”._ ME 37 Applied Heat Power Engineering. Prerequisite, ME 30. A course for senior mechanical engineering students given in two parts. Part 1--Steam Turbines. Three hours a week for one semester are devoted to a thermodynamic study of turbines. Various types of turbines are examined; nozzle design problems are solved; velocity diagrams for impulse and reaction turbines are developed, and the characteristics and design features of turbines in general are studied. Part 2--Internal Combustion Engines. Three hours a week for one semester are devoted to a study of internal combustion engines, including gas, gasoline and Diesel engines. The various air standard cycles are studied. Ignition, carburetors and injection mechanisms are discussed. The design features of the various engine parts are considered. Attention is paid to the cooling and lubrication systems. _Text: Barnard, Ellenwood and Hirshfeld, “Heat Power Engineering”, Vol. 1 and 2._ ME 50 Mechanical Laboratory. Prerequisite, ME 34. A course for senior mechanical engineering students. The course consists of one hour of lecture and six hours of work in the experimental laboratory. Studies and tests are conducted on steam engines, turbines, condensers, boilers, gasoline and Diesel engines and hydraulic equipment. Air compressors and refrigeration units are examined and tested; the flow of fluids is studied; oils and fuels are tested. _Texts: Shoop and Tuve, “Mechanical Engineering Practice”; Department Laboratory Manual._ ME 55 Mechanical Engineering. Prerequisite, ME 31. This course in heat power engineering is for students in chemical, civil and electrical engineering. Classroom theory is correlated with practice in the laboratory. Part 1.
