Students frequently confuse and incorrectly apply the several "deltas" that are used in chemical engineering. The deltas come in three different flavors: "out minus in", "big minus little" and "now versus then." The first applies to a change in a stream property as the stream flows through a process. For example, the "[delta]H" in an energy…

Solid-liquid and liquid-liquid mixing experiments have been developed to provide students with a practical experience on suspension and emulsification processes. The laboratory focuses on the characterization of the process efficiency, specifically the influence of the main operating parameters and the effect of the impeller type. (Contains 2…

A common undergraduate chemical engineering experiment has been modified for on-line operation over the Internet. By adopting rapidly changing Internet and object component technologies, we developed a novel approach combining the Internet and regular laboratory equipment. The client-server applications use a Visual Basic and Labtech programming…

Described are the essential elements of memos; suggested are a basic format for organization, and two problems to which technical specialists' memos seem particularly susceptible. Included is a memo assignment used in senior design classes and professional development seminars. (MVL)
