Statement I: A fluid flowing out of a small hole in a vessel apply a backward thrust on the vessel.
Statement II: According to equation of continuity, the product of area and velocity remain constant.
In the light of the above statements, choose the most appropriate answer from the options given below
Text Solution
Verified by ExpertsD
Both Statement I and Statement II are correct.
Due to small area of cross-section of the hole, fluid flows out of the vessel with a large speed and thus, the fluid possesses a large linear momentum. As no external forces acts on the system, in order to conserve linear momentum, the vessel acquires a velocity in backward direction or in other words, a backward thrust results on the vessel.
