Abstract

The hydrodynamic properties of helium ii have been studied by observation of the flow rate in a narrow slit between two flat glass plates. The isothermal, pressure-induced flow rates have been measured with hydrostatic pressures up to 2300 dynes/ ${cm}^{2}$ , at temperatures between 1.39 and 2.10°K, and with average slit widths of 2.4 and 4.3 microns. For a fixed pressure head, the observed flow rates have the same temperature dependence as the superfluid concentration in helium ii. At pressure heads below 1600 dynes/ ${cm}^{2}$ the flow rate is proportional to a power of the pressure. This power is nearly independent of temperature, but may be a function of slit width.
