What is the flame speed for propane gas?

5 inches / sec
11 inches / sec
12 inches / sec
15 inches / sec

The correct answer is: 11 inches / sec

The flame speed for propane gas is referenced as 11 inches per second. This measurement is significant in understanding how propane combusts and spreads when ignited. Flame speed is critical for safety and efficiency in gas installations. An accurate flame speed measurement helps gas fitters assess the proper settings for combustion devices, ensure that appliances operate correctly, and minimize the risks associated with gas leaks or incomplete combustion. Flame speed can vary depending on several factors, including gas mixture, temperature, and pressure, but 11 inches per second is a commonly accepted value for propane under standard conditions. This speed allows for predictable behavior during combustion, which is essential for proper appliance operation and maximal efficiency. Understanding flame speed also aids in developing safety protocols for handling and utilizing propane gas in various applications. In contrast, the other options do not reflect the established flame speed for propane, which is a vital parameter gas fitters must be familiar with to ensure safe practices in their work.
