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 lube is reported to operate with air entering at 5 bar and 20oC. and air streams leaving at 27oC and -22oC. both at (atm). The mass flow rate of warm air leaving is 6 times that of the cool air. .Are these results possible? Assume air to be an ideal gas at the conditions given?
