A 30 foot diameter circular pool fire of Dioxane (C4H8O2) is burning in a confined area. What is the heat release rate for the pool fire assuming a combustion efficiency of 100%? Round to the nearest megawatt.

Answer 1

To calculate the heat release rate for the pool fire, we can use the following formula:

Q = (π/4) x D^2 x H x ρ x Cp x T

where
Q = heat release rate (in watts)
π = 3.14
D = diameter of the pool fire (in meters) = 30 feet = 9.14 meters
H = height of the flame (in meters) = assume 1 meter
ρ = density of dioxane (in kg/m3) = 1180 kg/m3
Cp = specific heat capacity of dioxane (in J/kg.K) = 1700 J/kg.K
T = temperature rise (in K) = assume 500 K

Substituting the values, we get:

Q = (π/4) x (9.14)^2 x 1 x 1180 x 1700 x 500
= 1572288700 watts
≈ 1.57 megawatts

Therefore, the heat release rate for the pool fire is approximately 1.57 megawatts, rounded to the nearest megawatt.
