How do you get explosive Temp?
-
As you can see here https://powdertoy.co.uk/Discussions/Thread/View.html?Thread=10493 I am making a program that sets various constants in TPT. Explosive temperature (the temperature of the flame that results from the detonation of C-4 for example) has eluded me. I can figure out explosive pressure, and various other temperatures. However the method used to derive the explosive temperature 922 degC has eluded me. Unlike other temperatures it is not stored in a single precision floating point constant. Please help me figure out how that 922 degC is calculated for explosives.

I'm kind of sure that there is no variable or anything for that. I think changing the constant for fire will change the explosive temp. I'm not sure though. -

Then I guess I'm incorrect.
@videogamer555 Completely disregard my above post. -
Anyone have any idea on this?

How is the temperature for burning C4 determined then? The equation must use some kind of constant.

Perhaps it is with the coding that makes it explode faster than the fire moveslike with a good size blob of c4 when one pixel is lit it sets off a chunk of the c4 every frame instead of having the c4 become a pixel of fire and that pixel sets off the others touching it and so on

The equation for fire temperature is:
parts[r>>8].temp = ptypes[PT_FIRE].heat + (ptypes[rt].flammable/2)
Some relevant constants:
ptypes[PT_FIRE].heat = R_TEMP+400.0f+273.15f = 695.15
ptypes[PT_C4].flammable = 1000; (stored as integer not float)
Example:
695.15+1000/2 = 1195.15 K = 922 deg C
