Abstract
A simple level-sensing device is described for probing the profile of the chemical potential along the flowing liquid He II film. Measurements with these probes indicate that dissipation in the flowing film may occur either at highly localized regions or over extended regions of the flow path, depending upon experimental variations. Also it is shown that changes in transfer rate occurring during a given flow process are accompanied by a redistribution of the sites producing dissipation.Keywords
