pump driven by an air motor, shown in Figure 9.The gear pump is a constant volume device. Theory predicts that if driven at twice the speed,twice the volume flow rate would be produced regardless of pumping pressure. In reality theincrease in pressure leads to internal leakage, which is reflected as a reduction in volume-per-revolution in the data and graphed. The inlet suction pressure also varies with the flow rate dueto fluid friction in the inlet hose. This lab investigates both the pump internal leakage rates andthe tubing pressure loss.In performing this experiment, an air motor turns the gear pump. At the pump outlet is a ballvalve that creates a restriction and thus a pumping load. A rotameter is used for measuringvolume flow rate of

wereapproximately 75 students enrolled in the course during the first run. One lecture section isoffered each semester of the first run. To measure the effectiveness of each type of equipment,both qualitative and quantitative data are being collected from the students. The quantitative datacollected included exam scores, laboratory report scores, concept inventory, and satisfactionsurvey. The concept inventory was based on the test by Bristow et al. 11 The qualitative dataincludes laboratory observation and student reflections included in their individual laboratoryreports. The data between the two groups were analyzed for differences in overall courseperformance as well as the attainment of the objectives listed in the experiments above

strongcollaboration with an individual lab instructor, as even the best experimental apparatus will notbe used if an instructor does not see the value of incorporating it into their course. It also seemsthat teams who incorporate pedagogical research produce more sophisticated apparatus from adesign perspective. Finally, reflections of the students involved in the development of theseexperiments are examined in order to gain insight into how students perceive and usepedagogical information in their designs.IntroductionIt has been established by a number of authors that laboratory experiments and experimentalapparatus can be effectively designed by undergraduate students. There are a number of reasonsto use undergraduate students to create lab experiments

. The planetary gearset is the centerpiece of thebench-scale hybrid powertrain, which our students are completing over the course of fivesemesters. With the successful completion of the planetary gearset, our students are now readyto begin tackling the challenge of developing an overall control strategy for the hybrid system.AcknowledgementsThe authors wish to acknowledge the support of the NSF-TUES program in the Division ofUndergraduate Education, DUE-1044532, which made this research possible.

students computed the potential energy due to gravity (requiring firstnumerically integrating the angular velocity data), and then the total mechanical energy (sum ofkinetic and potential energies). That sum immediately reveals that the mechanical energydecreases with each cycle (Fig. A2(b)). We further asked our students to reflect on thisexperimental fact and to propose the mechanism(s) responsible for this dissipation. Thisnaturally led them to the phenomenon of rolling resistance of tires and the real (adverse) effectsthat rolling resistance has on vehicle energy consumption and greenhouse gas emissions! Thepoint is that the four often-misunderstood concepts concerning the dynamics of rigid bodies werereadily captured in this simple in-class

volunteered likely felt strongly oneway or the other about the experiment. In the future, the authors will consider administering theMCI to the same students before and after the experiment. Page 26.313.11In addition, the experiment guide distributed to students will be altered. Though the guide willnot be collected for grades, additional open-ended questions will be posed. This will give thestudents the opportunity to better reflect on what they have learned and may likely improve theconceptual results of the experiment.Finally, the MCI is multiple choice and therefore not necessarily the best method to showconceptual understanding. In addition to

In addition, despite the slower upload speed of theBeagleboard-xM, the total amount of time required to complete DSP hardware-basedlaboratories using the Beagleboard-xM was reduced by 6.6%. Further, and perhaps mostencouraging, is that results suggest even a one-time lab experience with the Beagleboard isenough to overcome any learning curve it might have and thus accelerate lab completion.Finally, comments and feedback solicited from students and teaching assistants reflect positively Page

. b) Modify the house parameters in the m.file to reflect the provided dimensions of the incubator. Save all the changes. After this file is run, the values of all the parameters will be in the MATLAB workspace and SIMULINK can use these values in the model built next. c) Build the incubator model in SIMULINK, using thermal parameters defined in the .m file. The subsystem should have two inputs: heat (power) flowing in “Qin” and the outside temperature “Tout”; one output: the air temperature in the incubator “Tincub”. Mask the model as a subsystem. d) Add the calculation of the bulb parameters Rf, Rb, Cf, Cb, and ReqBulb into the same
