    "abstract": "In the selective withdrawal experiment fluid is withdrawn through a tube with\nits tip suspended a distance S above a two-fluid interface. At sufficiently low\nwithdrawal rates, Q, the interface forms a steady state hump and only the upper\nfluid is withdrawn.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 transition the hump curvature\nbecomes very large and displays power-law scaling behavior. This scaling allows\nfor steady-state hump profiles at different flow rates and tube heights to be\nscaled onto a single similarity profile. I show that the scaling behavior is\nindependent of the viscosity ratio.",
