Propane is mixed 20% excess air (propane air mixture is initially at 25 C and 2.0 atm) and combusted at atmospheric pressure. It is assumed that the heat transfer between the chamber and the surroundings is negligible. In addition, you may assume that heat capacities of the gases are constant and that the reaction proceeds to 100% conversion.
a) Determined the flame temperature of the burner
b) Determine the flame temperature if 25% of the heat generated by combustion was lost through heat transfer to the surroundings?
heat capacities - Nitrogen 29.12 J/molk, oxygen 29.32 J/mol K, propane 74.92 J/ mol K, carbon dioxide 37.14 J/mol k, and water 33.57 J/mol k
