Confusion with adding water and ethanol:combustion reaction
Posted: Sun May 17, 2020 12:45 pm
I want to start by saying I'm a mechanical engineering student who just covered combustion in my Thermodynamics II course and I want to start a personal project (so chemistry is not something I am completely comfortable with just yet).
I want to simulate adding 25% water by weight to ethanol for a combustion reaction (with liquid O2 as the oxidizer). How does one balance this combustion reaction so that I can find things like the Lower and Higher Heating Value, the pressures, and other values of interest where I believe it's crucial to account for the water added to the ethanol.
So far I have my chemical equation (by mols) as,
0.75(C2H5OH)+0.63986(H2O)+O2 ---> x(CO2)+y(H2O)
I'm not sure if this is the correct way to account for the water added into the ethanol, and I can't seem to figure out how to balance this equation. Could I get some guidance on this topic?
Thanks,
Peach
