Questions
Point A is at a depth h below the free surface of water and the pressure at A is . B is another point at an additional depth x below A and pressure at B is . If the atmospheric pressure is equivalent to a water column of height h, and , find x.
detailed solution
Correct option is A
PA=P0+pgh, PB=P0+pgh+x∴P0+pgh+x=2P0+pgh⇒x=P0pg+h=h+h=2hTalk to our academic expert!
