Example text

Heat flow through a rod depends upon its diameter. Thin wires do not transfer much heat. For continuous heat flow, heat must be conti~luallyadded to the hot side (T,). Likewise, the cool side (T,) must be attached LO a heat sink. Otherwise, the flat plate or rod will reach thermal equilibrium with the environment. That is, the both reach the same temperature. FLAT PLATE ROD T2 Figure 2-5. The arrow indicates the direction of heat flow. The hot side is labeled as T, and the cool side as TI. Heat 29 The thermal conductivity is an inherent property of the material (Table 2-3).

As a result, liquids will maintain their temperature for a very long time. SILVER COATING SILVERED INSIDES GLASS HOT OR COLD LIQUID - EVACUATED REGION Figure 2-1 1 . A thermos bottle (dewar). 4. HEAT SOURCES Some sources are easy to quantify. The solar spectrum, energy content of fossil fuels, and calibrated blackbodies have known outputs. Other sources can only be described in qualitative terms. The heat source injects heat into an object and this raises the object's temperature. " Specific temperature distributions are discussed in Chapters 10 through 20.

389~10-~ = 4186. Note that I J = 1 w-s and 1000 cal = 1 kcal. Kelvin (K) is the SI unit of temperature. In many texts, it is replaced with degrees Celsius ("C). This does not change the conversion factors since all quantities are based on temperature change: if T, -TI = lK, then T,-TI = 1°C. 6. REFERENCES 1. H.

DETECTION OF RADIATION The term radiation refers to the continual cmission of energy fiom a surface.
