Abstract
The pressure of flowing liquid HeII has been measured in the capillary link as well as on its ends. Flow under gravitational and thermal potential has been studied in narrow slits and tubes packed with fine powder. On the basis of ordinary pressure measurement the results are not consistent and it is concluded that the definition of "pressure" in superflow requires additional parameters.Keywords
