I need help with a Fire Science Engineering homework. A fuel has heat of combustion equal to 30 kj/g. How much energy is released when 5 kilograms are oxidized? Assuming the fuel is reacted in 10 minutes, what is the average heat release rate for the fire? This will be greatly appreciated. Thanks.
Assume enough oxygen supply all this time.
30 kj/g*(5*1000g)=150,000 kj
This happened in 10 minutes, or 600 sec.
So the heat release rate is 150,000/300
=500 kj/s
