Morphology
The noun 'viscosity' already labels resistance to flow and the adjective 'dynamic' denotes relatedness to forces or motion, so the phrase straightforwardly signals resistance to flow under applied force or motion. It is a technical term with precise scientific nuance, but its basic meaning is compositionally predictable for a B1 learner who knows both constituents.
Etymology
The term dynamic viscosity starts with viscosity, a word from the idea of 'stickiness' in a liquid, and adds dynamic, a word about movement or force. Think of stirring honey: because it is sticky you must push harder, so dynamic viscosity measures how much a fluid resists motion when you push it, that is, its 'resistance to flow'.
