. Suppose we write Q ? hAΦT .We plan to exchange heat between the exhaust manifold and the ambient air, and weassume T∞ =100 ″F. Ducting will carry the air from the front of the vehicle to theexchanger. We estimate the available heat transfer surface area at about 1 ft2 (is this Page 15.1018.15reasonable?). We select an arbitrary value for the heat transfer coefficient, say 100Btu/(hr ft2 °F); although this is too large to be realistic, we find Q=(100)(1)(900)=90,000 Btu/hr.This rate of heat transfer corresponds to about 35 hp or 26 kW. If this were realizablewe would not need much of an IC engine at all! However, it is likely

A small Q hydrogen cylinder(with an internal volume of 14.7 L filled with compressed hydrogen at 2000 psi) wasused to power the fuel cell for slightly less than one hour. This power was adequate topower the e-Gator and prevent the batteries from losing charge. Pictures of the vehicleare shown in figure 3 below. Figure 3.

. Thework-load for the grader was quite extensive and timing became difficult to track based upon theamount of information exchanged. This process was improved by posting the reviews and therebuttals on the actual article, but the grader’s handling of paperwork was still quite extensive.The Public Knowledge Project has an Open Journal System that has been developed to improvethe review process (http://pkp.sfu.ca/?q=ojs). In the future this system may be used to helpfacilitate the review process.Continuing DevelopmentWhile this approach can be adopted for different courses, one issue with this technique is thelack of exact repeatability in the same course. Future students will not be starting from scratch inwriting the wiki textbook as the first set
efficient heat transfer. The rate of heat transfer is proportional to the exposed surfacearea (q=hAΔT), and skin contains a microcapillary network that substantially increasesthe exposed surface area for enhanced heat transfer. In this hands-on laboratory activity,students create artificial skin by encapsulating cotton candy in an elastomer. The cottoncandy is then dissolved away, leaving a networked path mimicking a microcapillarynetwork in skin.3.2 MaterialsThe following materials are required for this activity: a cotton candy machine (e.g. aNostalgia Electrics Cotton Candy maker, ~$50) modified with a rotational potentiometerplaced in series with the heating and rotational elements to vary the output temperatureand speeds; Jolly RanchersTM

Description of StudyThe author’s ChE program offers two required unit operations laboratory courses to its students:a four credit hour junior unit operations course (CHE 330) requiring three technical oralpresentations, as well as a two credit hour senior unit operations course (CHE 331) requiringthree technical oral presentations. In both courses, student presentations are scheduled to last for20 minutes (10-20 slides) followed by a 10 minute Q&A session with questions asked by theinstructor and fellow students enrolled in the section. Students are required to attend
these sessions, the course instructors discussed the course objectives,expectations, topics to be covered, and the outline of the course. By learning about their coursesand meeting their professors in an informal environment, students could begin their courseworkwith more confidence and accurate expectations, aiding their overall performance in thesecourses. During the morning of the second day of camp, the chemical engineering upperclassmanheld an informal Q&A session regarding course scheduling to give the rising sophomoresfeedback and suggest a plan for the academic trajectory for the remainder of their college career.By developing this plan, camp attendees could begin to anticipate coursework necessary forpotential double-majors, minors
