Venturi Effect - Wikipedia
Where is the density of the fluid, is the (slower) fluid velocity where the pipe is wider, is the (faster) fluid velocity where the pipe is narrower (as seen in the figure). Choked flow [ edit ] The limiting case of the Venturi effect is when a fluid reaches the state of choked flow , where the fluid velocity approaches the local speed of sound . ... Read Article
