ConclusionA series of web-based exercises were developed to support an introductory electrical and computerengineering class for first-year students. These exercises give students an opportunity forasynchronous learning in the topics of resistive circuits, RC circuits, 555 timers, andcombinational logic circuits. Student and faculty evaluations are very favorable.Bibliography1. I. Batarseh, Q. Zhang, R. Eaglin, Z Qu, P.

The latent heat removal associated with this moisture removal can becalculated from the following equation 9:q l = 0.68(cfm )(∆W ) (3.8) where q l = latent heat removal (Btu/hr) ∆W = moisture removal (gr/lb)Cooling coils often have low latent capacities, usually ranging from 20% to 30%. This high coilsensible heat ratio can create problems when the SHR of the load falls below 70 %, since the coilwill no longer have enough latent capacity to meet the latent load 5. These cooling coils cool theair to levels between 43 and 45 o F . Below that point, frost begins to form on parts of the coil,spreading slowly

The raw data in Figure 4 can be used to estimate the thermal energy absorbed by eachcollector using basic specific heat equations. “Q = 1.1 x cfm x ∆T” is a simplified calculation forair at atmospheric conditions that is commonly used for HVAC work. Q is the energy transfer inBtu/hr, 1.1 is a conversion factor, cfm is the flow rate of atmospheric air, and ∆T is thetemperature differential displayed in Figure 4. At 2 PM on January 5, the

Figure 4 defines thevariables in equations (1) –(3) in terms of a venturi but they apply to the orifice as well. Figures 5through 7 shows plots of flow versus delta P, insertion loss versus flow rate and discharge coefficientversus Reynolds Number for the orifice and venturi. The results of these experiments indicate clearlythat the venturi will flow greater quantities of water for a given supply pressure with a lower ∆P andlower insertion loss.

The details of the spectrometer can be found inthose references in which dielectric relaxation mechanism has been studied using a resonant Page 6.666.23cavity in T011 mode. The main purpose of using this mode is because of a very high Q-value forthe resonant cavity. This makes the cavity very sensitive in terms of its perturbation of electricfield. Similar techniques using resonant cavities in different modes have also been used [5-9].A computer control system is used to monitor the temperature of the microwave resonant cavityvery precisely.II.

output voltage amplitude measurements can beaccomplished very simply by employing two AC voltmeters. However, most undergraduate teachinglaboratories are equipped with only one meter per station. Beams [3] has shown that with external circuitrycontrolled by a PC, one can multiplex the input and the output signals into a single voltmeter. He has cleverlydesigned a I-Q phase detector and incorporated it with his multiplexer to do both phase and amplitudemeasurement with only one digital multimeter. However, the frequency was limited by the phase detector toonly two decades of dynamic range and to a maximum value of 100KHz.In our system we employ the digital oscilloscope of the set up rather than the multimeter.

When C goes low, the data that was present in the latch is retained on the Q outputsregardless of any of the D input. The ALE bus is connected to the C input of the 74HCT573integrated circuit. When the ALE key is pressed, the ALE bus goes high and the LSB of theaddress on the address-data bus is passed through the transparent latches to the address inputsA0-A7 of the 2816. When the ALE button is released, the address is retained at the A0-A7inputs. The address-data bus is then free to pass data to or from the 2816 I/O pins.

Using Blackboard’s CourseInfochat facility, students can access a general chat area and also submit questions using a “Q&A”area of the chat applet. The instructor responds to the questions.
