For various plasma flux velocities specified on the lower boundary of the chromosphere-corona transition region, we find temperature dependencies of plasma concentration, velocity and pressure along magnetic tube with one end immersed in the chromosphere and the other end located in the corona. We also obtain stationary temperature distributions along magnetic tube. At each point of the distribution, there is a balance between the heating by the classical heat flux, the energy losses through the radiation of optically thin plasma and the energy transport associated with plasma flow. We then determine: the range of velocities at the lower boundary of the chromosphere-corona transition region for which generation of shock waves in the transition region is possible; the range of velocities at the lower boundary of the chromosphere-corona transition region, for which transition region can be cousidered in the classical collisional approximation, and the range of velocities at the lower boundary of the chromosphere-corona transition region, for which the heating regime is close to p = const and computed radiation values are consistent with the results of satellite observations of extreme ultraviolet (EUV) radiation from the transition region.
