Weband theoretical models exist for predicting the flow rate through tubes, but their validity is not well established. In this study, measured conductances of stainless steel tubes for flow rates of 10-a to 10-14 mo/ s-1 with several inert gases are compared with various experimental and theoretical models of gas flow in the molecular, viscous and WebIn laminar flow, the fluid moves quickly near the center of the tube but roughly rests near the walls; this develops a parabolic velocity profile (parabola like x^2 or a quadratic function for the un-initiated). This parabolic velocity profile means that velocity, a symptom of an opposite of resistance, grows with the square of radius.
