Combining with Flow velocity
I would like to suggest that this page is combined with the Flow velocity page. Mauxb 19:13, 21 June 2007 (UTC)

Unsure what Nabla represents?
Could anyone explain as to what Nabla represents on this page? It is also used in many of the other pages on hydrodynamics but is never explained. —Preceding unsigned comment added by 130.159.84.121 (talk) 10:56, 21 May 2012‎
