Beware it could ignite H2 if both H2 and O2 exists in the room! | Beware it could ignite H2 if both H2 and O2 exists in the room! | ||
| − | The | + | The heat energy of one road flare is 600kJ. Volume is constant in sealed rooms (8m^3 per one cube), as well as amount of matter, therefore only temperature and pressure are changed with heat energy, which is isochoric process. The equation for isochoric process is Q = Cv·n·ΔT, where Q stands for heat energy, Cv is molar heat capacity, n is amount of matter (in moles) and T is temperature. As a reference, one cubic volume of air (oxygen & nitrogen) at 100kPa and 20C has around 357 moles. |
For example, with oxygen that means that means that one flare per one cubic volume can raise from -66C and 70kPa to 20C and 100kPa. From 20C and 100kPa one flare per cubic volume would raise temperature to 106C and pressure to 129kPa. | For example, with oxygen that means that means that one flare per one cubic volume can raise from -66C and 70kPa to 20C and 100kPa.

Interestingly, this makes iron a theoretically better energy source than coal in [[Solid Fuel Generator | Solid Fuel Generator]] as 1 unit of coal generate 200kJ of energy and 1 road flare costs 1 iron. This depends on iron ore to iron conversion efficiency, and road flare to energy conversion method, and solid fuel generator heat energy output. Further testing required. | Interestingly, this makes iron a theoretically better energy source than coal in [[Solid Fuel Generator | Solid Fuel Generator]] as 1 unit of coal generate 200kJ of energy and 1 road flare costs 1 iron.
