Abstract
Measurements of dissipation versus velocity for the flowing helium film are reported. A new probe technique allows measurement of the dissipation as a temperature difference in a small region of the film. The data are interpreted in terms of the Langer-Fisher fluctuation model as modified for driven flow where we find .
