Introduction
... Read Chapter 23 through. You may be somewhat acquainted with the first half or so of this chapter because the material is covered in CE212. The equation development of particular importance to us is on Pages 757 through 760. It is built around Figure 23-8(a). Thus, there is a temperature gradient in ...

... In past lectures we found that the power draw (Wc) and the capacity (Qe) are important performance parameters for a compressor. If we can develop heat exchanger models that describe the heat transfer rate, we have a set of equations that are coupled together. For example, the evaporator heat transfe ...

... Thermal Radiation. The Rate at which an object radiates is given by the Stefan-Boltzman Law: Prad = ε σ A T4 where Prad : Power radiated in Watts A : Area of emitter (or absorber!) T : Temperature of emitter in K σ : Universal constant ( S-B’s constant) σ = 5.6703 x 10-8 W/(m2K4) ε : the emissivity ...

... Answer: Agree because 3 + 5 = 8 and 3 – 2(5) = –7, and we know that the system is graphed as two distinct lines that intersect at only one point. Teacher Tip: Some students might also note that the equations are different so the lines are distinct, and because they have one point in common they are ...
