Engineering 260
Mass and Energy Balances


This course provides an introduction to fundamental principles that govern the design and analysis of chemical processes. The conversion of mass and energy serves as the basis for the analysis of steady-state and transient behavior of reactive and non-reactive systems. Specific topics covered include a review of basic thermodynamics, behavior of ideal and real gases, phase equilibria, and an application of these principles to the concept of industrial ecology.

CAPACITOR PROJECT
First-year students in EGR 260, Mass and Energy Balances, apply their newly acquired skills tracking material and energy flows in the production of motor-run capacitors for air conditioning applications as part of an environmental impact analysis called Life-cycle Assessment (LCA). Students first explore what a capacitor is and how it works in many different applications—from cell phones to washing machines—then conduct library research including patents, peer-reviewed journal articles, and original sources.

Students trace every step in the production process, beginning with extraction of raw materials such as oil and zinc, following their transportation and processing around the globe, culminating in an assembly plant in Mexico prior to distribution to consumers and ultimate disposal. At each stage, students quantitatively estimate material and energy inputs and environmental impacts in terms of land use, toxic emissions to air and water, and greenhouse gas emissions.

The students' research will be incorporated in an art installation opening in May 2004 at MassMoCA, the Massachusetts Museum of Contemporary Art, as part of a collaboration with the cyberfeminist artist collective subRosa and Smith's women's studies course on youth culture and gender.
