Lab experiments This section describes three of the many possible student lab experiments that could be performed with this apparatus, from the very basic to the very advanced.2.1.Valve coefficient Flow (q) through a constriction is proportional to the square root of the pressure drop (ΔP) across the constriction q = Cv ΔP0.5, (3) where Cv is a constant (see [19], eq. 2.3.3). Water is allowed to drain from the tank of the apparatus through a small hole (the constriction) and the pressure drop

architecture5.For obvious reasons, it was necessary to minimize the cost and complexity of this project.Experimentation with SDR hardware and software has recently become widespread in theAmateur Radio community, where minimization of cost and complexity are similarly important.Much of this activity has been focused on the Near-Zero-IF approach, in which the RF band ofinterest is downconverted to the audio frequency range. A/D conversion is then performed by aPC sound card. The sound card’s two input channels, normally used as “left” and “right”channels for stereo sound recording, are used as “in-phase” (I) and “quadrature” (Q) signalprocessing channels as shown in Figure 1.

Levene’s test was performed to ensure homogeneity of variance, and q-q plot wereexamined to ensure normality. We also computed effect size w2 for significant factors. IfANOVA showed significant differences, we performed Tukey’s HSD post-hoc test tocompare between groups. We did not explore differences between groups of different gendersor grade levels because the sample was rather homogeneous in terms of these attributes.FindingsResults of the entire surveyOverall, the summer academy participants thought DET was important (M=3.47, SD=0.35)(please note that 4 was the highest possible score, and 1 was the lowest
