How water comes out from the cell ?

Text Solution

Verified by Experts

The correct Answer is:
D
As vessel is falling freely under gravity, the pressure at all points within the liquid remains the same as the atmospheric pressure. If we apply bernoulli's theorem just inside and outside the hole, then
`P_("inside")+(rho_("inside")^(2))/(2)+rhog_(eff)y=P_(outside)+(rhov_(outside)^(2))/(2)+rhog_(eff)y`
`V_("inside")=0,P_("outside")=P_(0)` [atmospheric pressure]
Therefore, `V_("outside")=0` i.e., no water comes out.

A cylindrical vessel of height 500mm has an orifice (small hole) at its bottom. The orifice is initially closed and water is filled in it up to height H. Now the top is completely sealed with a cap and the orifice at the bottom is opened. Some water comes out from the orifice and the water level in the vessel becomes steady with height of water column being 200mm. Find the fall in height(in mm) of water level due to opening of the orifice. [Take atmospheric pressure =1.0xx10^5N//m^2 , density of water=1000kg//m^3 and g=10m//s^2 . Neglect any effect of surface tension.]
