What is the typical flame speed for natural gas when measured in inches per second?

11 inches / sec
12 inches / sec
15 inches / sec
20 inches / sec

The correct answer is: 15 inches / sec

The typical flame speed for natural gas is around 15 inches per second. Flame speed is a critical property when it comes to the combustion of gases, as it influences how quickly the flame travels through a mixture of gas and air. This speed can affect how the gas burns in appliances, its efficiency, and overall safety in gas distribution systems. Understanding flame speed is essential for gas fitters since it helps them in designing systems that ensure complete combustion and reduce the risk of incomplete combustion, which can lead to dangerous situations such as the buildup of carbon monoxide. When working with natural gas, being aware of its flame characteristics, including its flame speed, is crucial for proper installation and maintenance practices, contributing to the safe and efficient operation of gas appliances.
