For a timed pressure drop test, the hole size drilled should be?

• A. #20
• B. #30
• C. #41
• D. #50

Answer: (C)

For a timed pressure drop test, choosing the correct hole size drilled is crucial for accurate testing results. A #41 drill size is appropriate as it allows for a controlled and specific amount of gas to escape during the test. This size is effective for ensuring that the pressure drop can be measured accurately over time, providing insights into the integrity of the system being tested. Using a hole that is too small could result in insufficient gas flow, making it difficult to obtain accurate pressure readings. Conversely, a hole that is too large may allow for excessive gas escape, which can lead to misleading results. A #41 size strikes a balance, enabling the technician to observe a significant yet manageable pressure drop that aligns with testing standards. This precision is essential when detecting potential leaks within a propane system, ensuring safety and compliance during the pressure testing process.
