review text: Previous experiments showed that the flow through an orifice die of dilute solutions of flexible coils in thick solvents is characterized by three flow regimes. In each regime, pressure drop \(P_ g\) scales with flow rate \(q_ v\) according to a specific law. The objective of this work is to show how these scaling laws can be related to molecular stress-producing mechanisms, via a similarity analysis based on pertinent structural models.
