The dynamics in the equatorial plane of models for the envelopes of Be stars are investigated, first by inverting the equation of motion to solve for the unknown force, F x (r), in addition to those arising from gravitation, rotation, and gas pressure gradient, required to produce a radial component of velocity having an assumed functional form. F x (r) is then determined for both beta velocity and a power-law velocity dependence, and for each the consequences for F x (r) of the assumptions of angular momentum conservation, Keplerian rotation, and the variation of kinetic temperature with r are investigated
