Abstract: Abstract As seen in the previous chapters, the role of the dynamic pressure in nonequilibrium phenomena can be highlighted in the ET6 and ET7 theories by ignoring other dissipative processes. These theories are particularly important for gases with the large relaxation time of the dynamic pressure. In this chapter, taking the role into special account, we study a steady flow of a rarefied polyatomic gas by the ET7 theory. It is shown that, in contrast to the Euler theory of perfect fluid, the ET7 theory predicts some remarkable effects on a flow due to the relaxation processes of the rotational and vibrational modes of a molecule. And thereby characteristic features of the ET7 theory itself can be clarified.
