Calculate the mass fraction stochiometric ratio for the combustion of Ethane (CHs) in air (20% v/v Oz 80% v/v N2) Given the following Atomic Weights for the elements and their valencies." Symbol Atomic Weight H Element Hydrogen Carbon Nitrogen Oxygen *Note these numbers have been rounded for ease of calculation. N 1 12 14 16 Valency 1 4 3 2 From the products of combustion from the burning of Ethane in air and given the lower calorific value of Ethane is 47.8 MJ/kg show your calculation to estimate the adiabatic stoichiometric flame temperature rise AT. For this calculation the following values for Cp can be used Constituent gas CO HO N Specific heat at Constant Pressure Cp J/kg/ K 834 2020 1040
