of the system and the surroundings. Based on this study, a change seems warranted forthe first and second laws analysis relating to the electrical work.BackgroundA typical thermodynamic problem is solved by the traditional methodology of analysis thatcombines the first and second laws of thermodynamics. The first law describes the principle ofconservation of energy and is defined as the net energy transfer into the system being equal tothe change of the total energy in the system. Although there may be minor differences indescribing the principle by different authors, the first law of thermodynamics is usually given ina general equation form as Q – W = ΔE or Qin - Qout + Win – Wout = ΔE for closed systems where

Instead,students must explore the meaning of the quantities involved, particularly heat and work, byexamining the refrigerator compartments. In other words, instead of investigating where theenergy is going to, students should question where it is coming from.It should be noted that the actual COP may also be defined in terms of the rate of energy transfer: Q˙ c COP actual

For this, water could be used for testing (explored later). Thissystem could be tested with major appliances such as refrigerators and ovens/stoves, with theidea being to store and redistribute the energy needed to heat the water.The potential energy that can be harnessed can be represented by the heat transfer equation Q = A × G × η × ΔTQ(BTU) = the amount of heat gathered and storedA = the surface areaG = solar irradiance (BTUs/hour)η = the efficiency of the solar paneΔT = the temperature difference between the panel temperature and the storage

frontend that contains a “down-converter,” which converts the RFsignals at the received frequency into two parts: the I signal (in-phase) and Q (quadrature) signal,which is 90 degrees out of phase (relative to I). To perform down-conversion, we use a Tayloedetector 6 . The detector is a simple, inexpensive circuit that does a complete quadrature down-conversion. The I and Q signals feed directly into the soundcard of the PC, where they areconverted from analog to digital signals using the soundcard’s A/D converter.Once converted by the soundcard, I and Q signals are demodulated. This process consists of thefollowing basic steps for receiving7-10. 1. Time-domain shift: while I and Q are in the time domain, their (center) frequencies are

Method, a series of two equations must be used. First, the log mean temperature difference must be found using the equation below: ∆T1 − ∆T2 (1) ∆Tlm = ln(∆T1 / ∆T2 ) where ∆T1 is the temperature difference at the hot fluid inlet, and ∆T2 is the temperature difference at the hot fluid exit. Once this is found, the overall heat transfer coefficient, U, is found using the equation: Q&= U As ∆Tlm (2) where
