What happens to flow rate if the volume of air increases while time remains constant?

Flow rate is defined as the volume of air that passes through a given area over a specific period of time. It is typically measured in units such as cubic feet per minute (CFM) or liters per minute (LPM).

When the volume of air increases while the time remains constant, the flow rate must correspondingly increase. This is because flow rate is directly proportional to the volume of air being measured; if you are moving more air in the same amount of time, the flow rate rises. For instance, if a system is designed to deliver 10 cubic feet of air in one minute, increasing that volume to 15 cubic feet in the same minute results in a flow rate that is higher.

Thus, the correct answer indicates that as the volume of air increases without altering the time frame, the flow rate indeed increases.
