    "abstract": "In the selective withdrawal experiment fluid is withdrawn through a tube with\nits tip suspended a distance S above an unperturbed two-fluid interface. At low\nwithdrawal rates, Q, the interface forms a steady state hump and only the upper\nfluid is withdrawn. When Q is increased (or S decreased), the interface\nundergoes a transition so that the lower fluid is entrained with the upper one,\nforming a thin steady-state spout. Near this discontinuous transition the hump\ncurvature becomes very large and displays power-law scaling behavior. This\nscaling is used to show that steady-state profiles for humps at different flow\nrates and tube heights can all be scaled onto a single similarity profile.",
