The grade distribution is shown in Table6. A statistical analysis similar to the one in Table 3 for “Course 1” is not given, due to the smallnumber of students in the course. Also, the project for this course is an individual effort. Eachstudent chooses their control system, and performs the modeling and analysis.

is the determination of theairspeed or flow rate in the duct model. The airspeeds are too small for the normal wind tunnelmeasurement system which makes use of the pressure drop in the wind tunnel converging sectionresulting from the Bernoulli effect. An indirect method is possible, by measuring the volumetricflow rate supplied to the rake manifold from the smoke generation system. If the totalvolumetric flow rate of air containing smoke is Q, then the average discharge velocity from Nidentical rake tubes will be U = Q/(NA), where A is the internal cross-sectional area of a singletypical rake tube. Since the exit tube flow must be properly balanced with the external airspeedfor so-called iso-kinetic injection, U will be approximately the

. c American Society for Engineering Education, 2021 Q Longitudinal Study of a Project-Based Learning Methods Replacement for Lecture Based Courses Introduction Incorporating project-based learning into first year experiences for engineering studentshas been shown to improve student motivation and success [1], [2]. Using hands-on projects [3],interdisciplinary projects [4], or implementing project-based learning approaches in courses [5]during the first-year of an engineering curriculum also improves student retention [6]–[8].Project-based learning enhances student learning, improves student self-efficacy [9] and betterprepares students for workplace challenges [10]. However
∞ 𝑅ℎ𝑒𝑎𝑡 𝑠𝑖𝑛𝑘 = Eq. (1) 𝑞, where 𝑇𝑠 is the average surface temperature of the simulator, 𝑇∞ is the air temperature in thetest section and q is the power supplied to the heater. The heat transfer problem is simplified asone-dimensional heat conduction that is normal to the wind direction. Additionally, thetemperature at the base of the heat sink is assumed to be the same as the temperature of thesimulator for simplicity. That is, the thermal resistance of the thermal interface material isneglected. Tꚙ T

It helped by creating internal competition. It hurt by dividing people and assets. 3. Helped- competition kept us driven and let us see other alternatives to problems. Hurt- split up the members that really wanted to work on the vehicle and not choosing members hurt team dynamics. 4. Helped- teams were able to show the other difficulties and problems that would be applicable to both. Required increased insight to produce two separate products. 5. I think it helped because we fed ideas off one another, but a consolidated team with those that worked

Guidelines for the research paper (Appendix C) and examples of past researchreports (from the previous FIRE course) are made available to the students for reference.Additionally, a list of online resources offering tips for creating attractive and effective researchposters and academic writing guides are distributed to further aid in preparing the finaldeliverables. The research poster session is held during the last lecture session. Teams present theirsemester’s work in a 7 minute presentation, followed by 3 minutes of Q&A with the audience.Team research reports are also collected at this last meeting.

temperatures, the water volumetric flow rate, and the air velocity weremeasured. The water-side measurements were used to calculate the heat transfer rate from theheat exchangers since that provided the lower uncertainty. Results for the four heat exchangersthat did not leak and had a non-zero water flow rate are shown in Table 1.Table 1. Heat exchanger performance results.
