    Chemical energy to enthalpy.

    Hi there, Sry for the hassle, I found the problem... I calculated the mass flow rate wrong at the side of the flue gases. That was the issue. stupid me... Thanks anyway.

    Chemical energy to enthalpy.

    Thanks for your reply Latexman, Well to be more precise flue gases are mainly N2, and Cp for N2 in that temperature range is around 1.3KJ/KgK. Still my big question is what's wrong with the my equations? The issue with using Cp as 1.3KJ/kgK is that the enthalpy will be far less then the...

    Chemical energy to enthalpy.

    Hi, I am new to this forum. I am Having an issue with regards calculating the enthalpy in flue gases leaving a furnace. I know the fuel Net Calorific Value (NCV) of 38MJ/kg and I need to determine Cp of the flue gases. Now assuming an adiabatic process constant pressure, hence no heat...
