PMF profiles for water inside SWNTs and their relationship with the flow and wet flux. (A) PMF profiles of water molecules along the axis of channel in several representative systems with δ = 1.5 Å (black), 1 Å (blue), 0.75 Å (red), 0.5 Å (magenta), and 0 Å (green). (B) Relationships of the flow and net flux with the height of the barrier ΔG in PMF profiles. The black and red lines are flow = 0.9 × ΔG^−1.85 and flux = 0.9 × ΔG^−1.61.
