What is Flame Height?

Flame height is the distance from the base of a fire to the top of the visible flame. It is an important parameter in fire safety and engineering as it relates to the potential for fire spread, heat release, and the effects on surrounding structures and environments.

Example Calculation

Let's assume the following value:

Step 1: Raise the heat release rate to the power of 2/5:

\[ 100^{2/5} \approx 6.3 \]

Step 2: Multiply by 0.235:

\[ 0.235 \times 4.64 \approx 1.09 \]

Therefore, the flame height is approximately 1.48 meters.
