A cylindrical vessel of height 500 mm has an orifice (small hole) at its bottom. The orifice is initially closed and water is filled in it upto 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 200 mm. Find the fall in height (in mm) of water level due to opening of the orifice. (2009) [Take atmospheric pressure = 10×105 Nm 2, density of water = 1000 kg m-3 and g = 10 ms 2. Neglect any effect of surface tension.]
