Why does velocity increase when water flowing in broader pipe enters a narrow pipe? |
|
Answer» In a stream-line flow of a liquid, according to equation of continuity, av = a constant, where 'a' is the area of cross-section and v is the velocity of the liquid flow. When water flowing in broader pipe enters a narrow pipe, the area of cross-section of the water decreases, therefore, the velocity of water increases. |
