✦ Synopsis

We report on observations of the onset of dissipation in superfluid 3He flowing through a single cylindrical channel of diameter d = O. 71xm and length L = 6.0 #m. We propose a model in which thermally activated phase slips in the order parameter can account for the observed onset of dissipation.

We have measured the resonant frequencies and bandwidths of two of the modes of transverse vibration of a kapton diaphragm separating two disk shaped regions of superfluid 3He-B of radius 2 cm and nominal height 100/zm The measurements agree well with theoretical calculations.

We have searched for the pressure drops which are a necessary consequence of the dissipation attendant textural motion in 3He-A when uniform bulk superflow exceeds a critical value. We find no reliable pressure signature at a level significantly smaller than expected theoretically. We have modified
