calculating combustion efficiency and estimating flame temperatures the combustion reaction

1. (55) When calculating combustion efficiency and estimating flame temperatures the combustion reaction is used. On a separate sheet of paper, write out the combustion reaction equation for: cellulose: C6H1005 + x(O2+3.76N2) ? y(CO2) + z(H2O) + k(N2) and nitrocellulose: C6H10O5(NO2)3+ x(O2+3.76N2) ? y(CO2) + z(H2O) + k(N2) 2. (5) How much less air is needed to completely combust the nitrocellulose compared with the cellulose in terms of moles? 3. (4) Using your resources on the internet. Can a flame with a temperature of 2000K melt steel? 4. (4) Using your resources on the internet. Can a flame with a temperature of 2000K melt aluminum?

(12) What is the average mass loss rate for the 2in and 5in fires in units of of kilograms per second and pounds mass per second? Note: the scale is reporting weight in grams. Pan size (kg/s) (lbm/s)2 in 5 in 6. (10) In the following picture from the FM Global fire test linked below, if the pallets are 3 ft wide how tall is the fire?
