I need help with homework in Fire Engineering. What flame height would result from a 3 megawatt fire located in the corner of a compartment? This help will be appreciated. Thanks.
How high is the room?
5 Feet. Hope that helps. Thanks.
To determine the flame height resulting from a 3 megawatt fire located in the corner of a compartment, you can use the correlation provided in the SFPE Handbook of Fire Protection Engineering.
The correlation is as follows:
Flame height (ft) = 0.033 * Q^0.42
Where:
- Flame height is the height of the flame in feet.
- Q is the heat release rate in megawatts.
Let's plug in the values:
Q = 3 megawatts
Flame height = 0.033 * (3)^0.42
Now, let's calculate the flame height:
Flame height = 0.033 * (3)^0.42
Flame height ≈ 0.033 * 1.304
Flame height ≈ 0.043 ft (or approximately 0.52 inches)
Therefore, the flame height resulting from a 3 megawatt fire located in the corner of a compartment would be approximately 0.043 ft or about 0.52 inches.
Please note that this correlation is an approximation based on empirical data and certain assumptions. Actual flame heights could vary depending on various factors such as ventilation, fuel properties, and compartment dimensions. It is always important to consult relevant fire protection engineering texts and standards for more accurate and specific calculations.
