This paper presents investigations on electron temperatures and potentials in steady and dilute plasma flows. The analysis is based on the detailed fluid model for electrons. Ionizations, normalized electron number density gradients, and magnetic fields are neglected. The transport properties are assumed as local constants. With these treatments, along an electron streamline, the partial differential equation for electron temperature simplifies as an ordinary differential equation, and two simple formulas for electron temperature and plasma potential are obtained. These formulas offer several insights, e.g., the electron temperature and plasma potential distributions along an electron streamline include several exponential functions.
