The Difference between “Forcing” and Heat Transfer
The inconvenient Skeptic
November 21,2010 John Kerr EXCERPT: This is a continuation of the series on Radiative Heat Transfer (RHT). The purpose of the series is to use normal life experiences to explain RHT. In this article I will explain the difference between “forcing” and the transfer of energy. They seem similar, but they are different. A useful situation to explain the difference is a cool afternoon with a partly cloudy day. The temperature is 10 °C (50 °F). Based on the previous article that temperature means that the air has a “forcing,” or radiative flux of 364 W/m2. As a normal human your surface temperature is 35 °C and your “forcing” level is 511 W/m2. LINK It is our attitude toward free thought and free expression that will determine our fate. There must be no limit on the range of temperate discussion, no limits on thought. No subject must be taboo. No censor must preside at our assemblies. –William O. Douglas, U.S. Supreme Court Justice, 1952 |
