A tank is filled with water upto a height of 8m. A hole P is made in the wall of tank such that water coming out of it travels maximum horizontal distance. Find the speed of water coming out of hole P.
The correct option is C2√2gm/s
We know, Range will be maximum when h=H2 ∴h=82m=4m Also, Velocity of efflux =√2gh =√2×4×g =2√2gm/s
