... a path that a fluid element would take. Three such streamlines are shown in the figure to the left. The velocity v of a fluid element is always tangent to a streamline, in the same way that the velocity of a moving object is tangent to the path at any point. Two streamlines cannot intersect. If they ...

... The supersuck bailer consists of an easilyretractable duct on the underside of the dinghy. As the dinghy moves forward, water flows through this duct. The passage inside the duct first converges and then diverges — in effect it is a ‘venturi’. The flow accelerated in the convergent section and its p ...

First, as intimated in Chapter 1, stratification is an essential ingredient of environmental fluid mechanics, and this implies that density variations, although small, can have significant dynamical effects. The astute student can then legitimately ask whether the n ...
