flow rates
Fluid passage measurements
Flow rates measure the volume of fluid passing a point per unit of time—gallons per minute, liters per hour, cubic meters per second.
Engineers calculate flow rates for water systems, blood circulation, fuel delivery, and industrial processes.
The flow rate through the pipe exceeded design specifications.
A higher flow rate means more fluid moving faster; a lower one means less or slower movement.
