The Betz conjecture, its extensions and applications, regarding the final rolled-up structure of a vortex sheet in the absence of viscous effects is reexamined. It is argued that the conjecture, and consequently, its extensions and applications are theoretically incorrect. A plausible explanation is provided as to why, inspite of its incorrectness, the results correlate reasonably well with flight experiments on wakes behind aircraft wings.
