Условие

A compressor blows air into Ranque-Hilsch T-shaped tube at a pressure of 0.5 MPa or higher so that the air begins to circulate. In such a case hot air is coming out from one end of the tube and cold air from the opposite one. Find out which end of the tube is the “hot” one and explain the difference of the temperatures obtained. Investigate the parameters this difference depends on.
