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? ![Roll Eyes :rolleyes: :rolleyes:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
