Question

Half of the liquid flows out of a vertically placed thin tube filled with a viscous liquid in time of 8 sec . After how much time (in sec ) will the rest of the liquid flow out? Neglect surface tension and assume that the liquid is so viscous that it is in steady state.

For steady state \displaylines m g = η ( 2 π rh ) dh dv ​ 2 π rh ρ π r 2 hdx ​ = η dh dv ​ dh dv ​ is independent of h. So time will remain same
