The mass transfer rate in U Gem at quiescence, estimated to be M≈1.3-2.0×10¹⁶ g/s, is used to calculate the amount of mass ΔM_tr transfered to the disk during quiescence. Light curves of U Gem are used to estimate the amounts of mass ΔM_accr accreted during its three types of outbursts. In the case of wide outbursts and the 1985 superoutburst ΔM_accr are much larger than ΔM_tr, indicating significant enhancement in the mass transfer by a factor of f≈20-50. There is no evidence for comparable enhancement during narrow outbursts.
