Which term refers to the capacity of the venting system to move gas under a given resistance?

• A. Flow
• B. Throughput
• C. Flow Rate
• D. Flow Capacity

Answer: (D)

The question is about the venting system’s ability to move gas when there is resistance in the path. Flow or flow rate describe how much gas is actually moving at a given moment (the real-time movement). Throughput is similar in idea but is often used in different contexts and doesn’t specifically capture the system’s capability under resistance. Flow capacity, on the other hand, is the rated ability of the system to move gas when faced with a certain level of resistance. It reflects the maximum or intended movement the vent can achieve given that resistance, typically expressed as a volume per time (like CFM) at a defined pressure drop. So the term that fits “capacity of the venting system to move gas under a given resistance” is flow capacity.
