Main Question or Discussion Point
Imagine that some object (a long rod for example) is flying in atmosphere very quickly. If we know its speed, altitude and also amount of time spent during flight-can we calculate the amount of heat emitted during this quick motion (due to atmospheric drag)? I would like to know if that object is melted/boiled or no the temperature can be calculated by means of this online-calculator here: http://www.grc.nasa.gov/WWW/BGH/stagtmp.html Now, how the emitted heat should be calculated? The temperature should be multiplied to time? And should we compare the received result to materials heat capacity?
