Q. A vented tank of large cross-sectional area has a horizontal pipe .12m in diameter at the bottom. The tank holds a liquid whose density is 1500 kg/m^3 to the height of 4.0 m. The velocity of the liquid in the pipe at point B holds a column of liquid to a height h. suppose the liquid is an ideal fluid in laminar flow.
