The laboratory instruction sheet (sometimes called a laboratory manual), together with the equipment used by students, is an essential resource for laboratory work. It has a direct influence over all the interactions that can occur in the laboratory activity, of which student-equipment is the only common synchronous interaction in both…

A remote-controlled experiment for power electronics was developed for a virtual laboratory. Power converter experiments were set up, allowing students to conduct a remote-controlled experiment with special hardware and electric power. Students can activate parameter controls, connect wires, and tune electric load conditions with preset electronic…

This paper describes in detail a successful training program developed for sessional (part-time or nonpermanent) laboratory demonstrators employed in the Electrical Engineering Department of an Australian university. Such demonstrators play an important role in teaching practical concepts and skills in engineering. The success of the program…

Background information, procedures used, and typical results obtained are provided for an experiment which: (1) examines the effect of residence time on conversion in a tubular flow reactor; and (2) compares the experimental conversions with those obtained from plug-flow and laminar-flow reactor models. (JN)

Describes a combustion laboratory facility and experiments for a senior-level (undergraduate) course in mechanical engineering. The experiment reinforces basic thermodynamic concepts and provides many students with their first opportunity to work with a combustion system. (DH)

Describes a semester-long project in which students designed, built, and operated an apparatus to separate particles by fluidization principles. Each laboratory group worked on a separate step of the design in a sequence selected by the instructor in a manner similar to the way a design team might function. (JN)

Describes a drying experiment useful in presenting the concept of simultaneous heat and mass transfer. Background information, equipment requirements, experimental procedures, and results are provided. The reasonably good agreement in the calculated rate of drying and that observed experimentally makes students feel confident in applying…

It is challenging for biomedical engineering programs to incorporate an indepth study of the systemic interdependence of cells, tissues, and organs into the rigorous mathematical curriculum that is the cornerstone of engineering education. To be sure, many biomedical engineering programs require their students to enroll in anatomy and physiology…

Discusses features of experiments (conducted during 1980-81 in the University of Edinburgh's third-year chemical engineering laboratory) which might make them attractive for wider use. Experiments focus on convective mass and heat transfer, diffusion, heat transfer to a jet, and adiabatic batch reactors. (JN)

Describes an experiment where equal parts of copper and aluminum are heated then cooled to show extremely large crystals. Suggestions are given for changing the orientation of crystals by varying cooling rates. Students are more receptive to concepts of microstructure after seeing this experiment. (DH)

Discusses a simple method for following the movement of a solute in an adsorption or ion exchange system. This movement is used to study a variety of operational methods, including continuous flow and pulsed flow counter-current operations and simulated counter-current systems. Effect of changing thermodynamic variables is also considered. (JM)

Describes a reaction system experiment utilizing saponification of ethyl acetate by sodium hydroxide. The activity is part of an undergraduate chemical engineering course. (SL)

Considers the deviation from the ideal flows of both a backmix tank and a backmix tank followed by a flow vessel. Background information, apparatus used, and experimental procedures are provided. Typical results are also provided and discussed. (JN)

Previously described a class experiment which employs the hydraulic analog to represent systems of first order reactions in batch reactors. The hydraulic experiments are extended to represent reaction systems with nonlinear systems. (JN)

As part of a project focusing on techniques in industrial chemistry, students carry out experiments on separating copper from cobalt in chloride-containing aqueous solution by liquid extraction with triisoctylamine solvent and search the literature on the separation process of these metals. These experiments and the literature research are…
