The following experimental data is available 393 242 02 (g) 30.26 90 i. Assuming that the fuel and air are fed to the combustion zone at 20°C, and the heat capacities are constant, calculate the adiabatic flame temperature (AFT). ii. Explain why the maximum AFT is achieved at 100% stoichiometric air ii. What assumptions are made in the calculation of the AFT? [33⅓%] 01:17 13/12/2018 15
