A Hilsch vortex tube operates with no moving mechanical parts and splits a gas stream into two streams: one warmer and the other cooler than the entering stream. One such tube is reported to operate with air entering at 5 bar and 20 degrees Celcius and air streams leaving at 27 degrees Celcius and -22 degrees Celcius, both at 1 atm. The mass flowrate of warm air leaving is 6 times that of the cool air. Are these results possible?
