The dependence of stellar mass loss on rotation for nonemission-line stars is investigated, confirming numerically an earlier result showing a seemingly good correlation between the stellar mass-loss rate (MLR) and v(rot)sin(i) but showing that this correlation merely reflects the distribution of MLR and v(rot)sin(i) over the Hertzsprung-Russell diagram; it is physically not real. An attempt is made to disentangle the dependence of MLR on the three variables: Teff, L, and v(rot)sin(i) by empirically determining the relation over the HR diagram. It then appears that, for each point in the HR diagram, MLR depends only weakly on v(rot)sin(i), in agreement with theoretical predictions. For Be and shell stars the MLR for their high-latitude parts follows approximately the same rule as the one valid for non-Be stars, while the MLR from their equatorial areas is larger by a factor 100, in rough agreement with a theoretical prediction.
