This explanation would require helium II to have an abnormally low viscosity; at present, the only viscosity measurements on liquid helium have been made in Toronto 1, and showed that there is a ...
The present data were obtained from observations on the flow of liquid helium II through long capillaries. Two capillaries were used; the first had a circular bore of radius 0 -05 cm. and length ...
In a liquid like water, the particles are randomly arranged. They move freely over each other, a bit like marbles in a bucket.This is why liquids can be poured. In a gas, like helium, particles ...
