143267 Water level is maintained in a cylindrical vessel up to a fixed height $H$. the vessel is kept on a horizontal plane. At what height above the bottom should a hole be made in the vessel, so that the water steam coming out of the hole strikes the horizontal plane of the greatest distance from the vessel ?
