What load does the #41 hole simulate in a timed pressure drop test?

• A. 50,000 BTU/hr
• B. 75,000 BTU/hr
• C. 100,000 BTU/hr
• D. 125,000 BTU/hr

Answer: (B)

The #41 hole simulates a load of 75,000 BTU/hr during a timed pressure drop test due to its specific dimensions and the restrictions it creates in the flow of propane. This hole size is calibrated based on industry standards to closely mimic the flow characteristics and pressures involved with a load of that magnitude. In a timed pressure drop test, the precise measurement of pressure drop is essential for assessing the performance and capacity of the propane system. The 75,000 BTU/hr load is significant as it represents a common demand scenario for many residential and commercial applications. This benchmark helps technicians evaluate if the system can maintain proper pressure levels and flow rates under standard operating conditions, ensuring safety and efficiency in propane distribution and use. Choosing this value allows technicians to follow regulatory guidelines and ensure that the system meets the necessary performance criteria for safe and effective operation.
