Abstract
Isothermal flow of He II in circular glass and metal tubes of inner diameter ∼0.2 mm is investigated. Different methods for the generation of the flow are used. The pressure heads required to drive the flow as well as the heat supply require to maintain isothermal conditions are measured. Earlier findings are confirmed and are shown to remain valid for smaller transport rates. The main features may be summarized as follows: (1) the pressure heads at given mass transport are almost independent of bath temperature, (2) they vary almost proportionally to the square of the mass flow rate, and (3) the flow becomes isothermal when there is a small, almost constant slip velocity (≲2.0 cm/sec) between the superfluid and normal components.
