In the earlier paper we showed that phenomena observed in a planar diode tube are explained by the electrohydrodynamics. In this note we shall discuss a steady flow of electron gas in a spherical dioae or a purely radial expansion or compression of electron gas. Situation is analogous to the expansion or compression of conventional fluid through the Laval nozzle and is complicated by the many. branches of the solution.<BR>When space charges are neglected then the expansion of electron as is identical to the expansion of plasma in the solar gravitationla field as discussed by E. Parker and we get exact analytical solution. However, when the space charges are not negligibly small, we have no longer any simple solution and hence we shall give the numerical solution by a computor.
