volume flow rate
Let an agent explain volume flow rate and its units and measurement, support calculations for pipes, channels and pumps, describe physiological flow rates in general terms, and support learning.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain volume flow rate and its units and measurement, support calculations for pipes, channels and pumps, describe physiological flow rates in general terms, and support learning.
The volume of fluid that passes through a surface or system per unit time, measured in units such as cubic metres per second or litres per minute, used for rivers, pipes and pumps, for the yield of wells, for ventilation and gas flows, for acoustic volume velocity, and in physiology for cardiac output and renal clearance; volume flow rate is measured with flow meters and gauging methods and is central to hydraulics, engineering and medicine.
What it is for: Volume of fluid per unit time.
It can be explain units and measurement; support calculations; describe physiological uses; support learning.
Distinguishing features

What it looks like
Not physical; a measured quantity.
How it is recognised
Volume per unit time
Cubic metres per second, litres per minute
Mass flow rate is mass per time; velocity is distance per time
