For the latter students, adetailed discussion of V-mixing and the convective and shear mixing involved in the processfollows. Figures 8 a and b are schematics of the polycarbonate V-mixer assembly and theV-mixer stand designed and constructed for a wide range of applications and mixer loads. Asthe Figure 8 b shows, the V-mixer rests on a rotating stand. Thus, no torque is directly appliedon the V-mixer. The pneumatic motor is connected directly to the v-mixer stand.

this lab is to not overwhelmstudents with material since a graphical user interface (GUI) requires concepts not covered in thelecture. To mitigate this, students are given a reference framework implementing more of thecomplex graphical components but with blank sections for students to complete. The framework for the C++ section of the course uses the Simple Fast Multimedia Library(http://www.sfml-dev.org) while the MATLAB section uses the built-in graphical user interfacemodule. These frameworks create a blank window, allow the user to control the mouse andkeyboard, and provide a graphical component to draw in (see Appendix A and B for examples).Note that students do not need to necessarily understand the framework to complete

judged to be inappropriate. The laboratory experience required a low-voltage replica ofcommercial three-phase power: sinusoids with 120° phase separation. The faculty design teamwas unable to find such a source commercially at low cost and designed, built, and tested severaldifferent sources. In addition to a transformer solution, two electronic circuits were implementedin the initial trials of the laboratory exercises: (a) digital synthesis using synchronized counters,D/A conversion, and wave shaping, and (b) digital synthesis using EPROMS and D/Aconversion. Each of these three-phase synthesizers was developed with an estimated parts costof less than US$10 (assuming appropriate DC power availability).The design and implementation of the sources
