Two cylindrical vessels V1 and V2 are placed on the same horizontal level. Each vessel contains the same
liquid of density ρ. Initially the vessels are not connected (valve closed). The height of liquid in vessel V1
is h1 and that in vessel V2 is h2. The diameter of vessels V1 and V2 are 2d and d respectively. When
vessels are interconnected (valve opened) at the bottom, the height h of liquid in each vessel (neglecting
the volume of liquid in connecting tube) will be
