Experiments on superfluidity flow through pinholes suggest that inhomogeneous nucleation of distorted vortex half-rings at the orifice lip ma u account for the onset of dissipation in such flows. This paper gives a calculation of the shape of the critical vortex-one whose local self-induced velocity matches the local flow velocity. The length and energy correction for a typical geometry amounts to more than 30%.
