Final answer:
In a properly adjusted propane system, an operating pressure test would show 10 to 11 inches of water column. This measurement ensures the propane is at the correct pressure for appliances to function safely and effectively.
Step-by-step explanation:
On a correctly adjusted propane system, an operating Pressure test will show 10 to 11 inches water column. This is a measure of the pressure the gas exerts and is a standard setting for many household appliances using propane. When conducting a pressure test, a manometer is attached to the appliance valve or regulator. The water column measurement indicates if the propane is at the correct pressure for optimal performance.
Understanding hydrostatic pressure is crucial in this context. Hydrostatic pressure is the pressure exerted by a fluid due to gravity. In propane systems, the pressure is measured in terms of water column inches because it is a more practical and safer alternative to using mercury, given the significant difference in density between mercury and water.
Pressure measurements are vital for safety and efficiency in propane systems. A gauge, or manometer, measures this pressure, and the readings can fluctuate based on temperature as described by Gay-Lussac's Law. Knowing the correct operating pressure is essential for maintaining a safe and properly functioning system.
