Abstract
It is shown that a momentum equation identical in form to that of the familiar Navier-Stokes fluid, can be derived for the fluid condensate of a weakly interacting Bose gas. For the condensate the pressure is given by the simple barotropic relation p= rho 2/4, while the anisotropic stress tensor sigma ij' depends only on the density and density of gradients.Keywords
