A vessel whose bottom has round holes with a diameter of d = 0.1 mm is filled with water. The maximum height of the water level h at which the water does not flow out, will be: (The water does not wet the bottom of the vessel). [S.T of water = 70 dyn/cm]
Text Solution
Verified by ExpertsThe correct answer is:
D
When the excess pressure at the hole becomes equal to the pressure of water height; then
only water will start coming out of the holes: [atm pressure on both sides is same].
⇒ ρ hg = 
⇒ h = 
= 
= 0.28 m.
