Recent Developments in Engineering Measurements LabAbstractOver the past two years, Engineering Measurements Lab has attempted to increase the breadthand depth of course material introduced to students to allow them to design and performsuccessful experimental tests. To reflect these changes, the course has grown from 1 unit to 2units. The following structural changes have been made to reflect the increased academic creditgiven in this course: (i) a single lecture contact hour per week was added, (ii) lab contact hoursfocus more on practical aspects of each lab, and (iii) the number of experiments run in the coursehas increased from four to seven. Material for each lab was delivered in a two week cycle with aone hour lecture and two hour lab period every week. Lectures in week “A” generally provide atheoretical description of the laboratory, while week “B” lectures stress a practical aspect of thelab. New lecture topics have been added to the course to introduce students to data acquisitionsystems and further emphasize measurement uncertainty and statistical analysis.In addition to the change in the content of the course, the Toyota A3 report format has beenadopted for all labs to expose students to a wider variety of tools for technical communicationand to foster a spirit of creative and innovative problem solving. In keeping with the iterativenature of these reports, the general process for each lab involves multiple events with feedbackcoming from peers and instructors. During the week “A” lab period, students are introduced tothe lab facility and perform an ungraded activity where they manually perform relevantcalculations using a small subset of data taken in previous offerings. They are then presentedwith a full set of previous data so they can create a spreadsheet to calculate and plot pertinentinformation. This prelab data exercise is submitted before the week “B” lab period. During theweek “B” lab period, students run the laboratory to generate their own data set. A draft A3 reportis then submitted prior to the following week “A” lab period. Students are given time to peerreview draft A3 reports before they perform the manual activity for the next laboratory. Labtopics for this course include, characterization of (i) vortex tubes, (ii) vapor compressionrefrigeration, (iii) centrifugal pumps, and (iv) frictional pipe losses. New labs have beendeveloped for this course examining (v) error propagation in measurement of complexgeometries, (vi) measuring Poiseuille flow velocity profiles, and (vii) thermocouple calibration.This work will describe the changes made to this course over the past two years and discuss thesuitability of these changes by examining their sustainability and how they impact ABET courselearning objectives, student performance, and student satisfaction. Plans for future developmentof the course will also be discussed.
