Qusestion 133) (50 points) Fuel indicated in column (1) at 25C,1 atm, ensers a wel-insulated reactor and reacts with air entering at the same temperature and pressure. For steady state operation and negligble effects of kinesc and potential energy, determine the tomperature of the combuston products for complete combustion with (a) The theorescal amount of air, (b) the percentage of thecretical air indicated in column (2) (see example 13.8) TAGLE 1 Complete combustion equations with cxigen: (When using air add 3.76 mol of N2 per mol of air ) Propane: C3H+5HO23CO2+4H2O Antach File QUESTION 2 Question 23) (40 points) Evaluate the chemical exergy of the fuel given below, at 25C, 1atm in k.l/kg. Using eq. 13.36 (reproduced below) evaluate the chemical exergy for an environment corresponding to the table 2 below, obeying the ideal gas model (composition in a molar basis) (see example 13. 12 ) Compare your results with the value of the Standard Chemical Exergy reperted in the book (2153 E3 kulkmol) by calculasing the ratio (Chemical exergy calculated)(Standard Chemical Exergy), What are your comments about this ratio
