A vent-limiting orifice is allowed to discharge approximately how much gas in a 24-hour period?

A vent-limiting orifice is a device designed to restrict the flow of gas to a specified limit, providing an important safety measure in gas installations. Its purpose is to ensure that in the event of a gas leak, the discharge of gas is controlled to minimize the risk of fire or explosion.

In the context of this question, the correct answer indicates that a vent-limiting orifice is allowed to discharge approximately 24 cubic feet of gas over a 24-hour period. This specific amount is significant as it reflects regulatory guidelines intended to ensure safety while still allowing for the necessary operational functions of gas systems. By limiting the discharge to this volume, it helps prevent excessive accumulation of gas in an area, which could lead to hazardous situations.

The choice of 24 cubic feet aligns with established safety practices, ensuring that the maximum allowable discharge does not exceed levels that could pose a risk. This regulation has been carefully considered by safety authorities to strike a balance between function and risk management.
