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.

  • engineering -

    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
