17. Compressible flow Even if air and other gases appear to be quite Compressible in our daily doings, we have until now only analyzed incompressible flow and sometimes applied it to gases. The reason is . as pointed out before that a gas in steady flow prefers to get out of the way rather than become compressed when it encounters an obstacle. Unless one entraps the gas, for example in a balloon or bicycle tire, it will be effectively incompressible in steady flow as long as its velocity relative to obstacles and container walls is well below the speed of sound. But when steady flow speeds approach the speed of sound, compression is unavoidable.
