inquiry activity was done during lecture in ChE 3084, a junior-level chemical engineeringcourse. The course content is roughly 2 credit hours of separations, 1 credit hour of simulations,and 1 credit hour of mass transfer. The experiment was to measure a diffusivity, to compare it toliterature values, and to develop of list of weaknesses of the experiment.The diffusivity is a measure of how quickly a compound moves through another due to aconcentration gradient. Fickian diffusivities of alcohols in air are on the order of 1 x 10-5 m2/s atroom temperature [1]. Experimental data were analyzed with the concept of diffusion time, inwhich the time for a molecule to diffuse an average distance in one dimension is given byEquation 1 [2

This includes measuring its propertiesboth before and after cooking (e.g., [1-3]). Considerable literature exists for measuring theproperties of both cooked and uncooked pasta (e.g., 4-6). To the authors’ knowledge, theexperiment described here is not done by pasta manufacturers to determine any properties. In theuncooked state, pasta

results for the characterization of a hybrid systemwhich includes a hydrogen fuel cell (HFC) along with a battery in a hex-copter drone configurationto determine its effectiveness. The reason for the use of hydrogen relies on the fact that it has ahigher energy density (120 kJ/g) than commercial lithium-ion polymer batteries (LiPo), the typeof batteries most civilian drones currently use, which only have an energy density of 1 kJ/g. Inorder to test the HFC, a testing setup composed of lightbulbs was created in order to determine thefuel cell power output and its interactions with the battery system. The data used for the analysisof the performance of the drone was the power drawn over the duration of each test. The resultsshow a delay of less

Both allow flexibility andhave their benefits and drawbacks. Before moving further, three things are of note. First, theusage of “Arduino” will refer to the Arduino code and hardware as a system. Second, LabVIEWis a coding environment where the user creates a “VI” or virtual instrument. However, manytimes “LabVIEW” will be used as the name of the code. LabVIEW is based on a language calledG [1]. Finally, while these DAQ systems don’t require much programming knowledge, a basicunderstanding is needed.

These are skills that institutions deem important for their students’ future. For example, theUniversity of Central Oklahoma (UCO) relied on the theoretical base of transformative learningto develop their Student Transformative Learning Record (STLR) [1]. The transformativelearning theory is based on the work of Mezirow which argues that in order for authentictransformation to occur, learners need to reflect on their relationships with themselves, others,and the world they live in. Learners may have transformative experiences if they are willing toexplore other ways of thinking [2]–[4]. The STLR focuses on six tenets

Conferenceprocess of pool boiling provides insight into significant improvements in a surface’s ability totransfer thermal energy to a fluid. The motion that occurs near the surface in boiling is due to amix of bubble growth and bubble detachment. Buoyancy forces cause the vapor bubbles to risethrough the liquid and eventually escape the surface. From boiling, there is a sustained amount ofheat transfer from the solid surface during the change from the liquid to the vapor state. [1] Duringthe process of pool boiling, different boiling regimes can be understood using a boiling curve.The pool boiling process allows a better look into the fundamental mechanisms that play a role inboiling. Free convection boiling occurs at the beginning of boiling and can be
