Morphology

flow + rate

The meaning 'volume of fluid per unit time' is directly derivable from combining 'flow' (movement/amount of liquid) with 'rate' (amount per unit time). This noun+noun measurement pattern is transparent and common cross-linguistically and in technical contexts, so a B1 learner who knows both constituents will most likely understand the MWE.

Etymology

The noun flow rate paints a simple picture. The flow is the moving water (or other liquid) and the rate is how much of it passes a point in a certain time, so it means 'how much liquid moves past a point in a certain time'.
