Summary: The application of symmetry analysis to hydrodynamics is illustrated by two examples. The first one is a description of all irrotational barochronous motions of ideal gas. The second is an exact solution of magnetohydrodynamics equations for infinitely conducting media, which describes the flow of the so called “special vortex” type.For the entire collection see [Zbl 1066.53003].
