I am an new EE with my FE, but my thermo knowledge is lacking in many areas. Its one area where i would like to become an expert. So i try to find ways of applying thermo analysis on my free time to imprve my skills. where here is one and I have no idea where to even start.
a youtuber with a large following goes into the woods on his spare time and trys to make things from scratch building off previous things made in previous weeks. he is trying to smelt iron using his own designed forge
here is the youtiube video of him collecting the material and adding flux to attempt to reduce the melting point.turn on Closed captions in the bottom right of the screen, he doesn't talk but adds subtitles for simple explanation (and maybe even inaccurate information). The charcoal he uses was made by him in a previous video. So whatever the natural specific heat of charcoal (carbon graphite) is 0.71 (kJ/(kg K))
it seems like the slag left over at the end didnt get anywhere near hot enough to be extract most of the iron. how do i approach attempting to calculate the temperature of the furnace? i would assume just looking at this from the most basic PV=nRT he should cover the top to increase the pressure, but would that be enough to reach the ~1500*C needed to melt it? mathematically how does the temperature correlate with the air flow?
i know measurements of everything isn't given in the video but if some scratch paper calculations were to be done how would I start? if the design can't reach 1500*C any general design that would be better?
thanks
