I guess my issue is that, I could solve the differential equation i found but is there a way I should be able to figure out k that doesn't involve physics?
Okay, so PV=nRT and with a density of 1250g/m^3 and a molar mass of 29 ish for air I ended up with the EQ Pressure=m_ag/(RT) and plugged in some reasonable numbers to get K~1/8. Is this a viable path? Using this constant i get an altitude of ln(2)/k=ln(2)/(29*9.8/(273*8.314))...
Sorry guys, I am not too bright and I am trying to learn diff eq on my own (have the class next year) and I am hung up on this problem:
If the density of air at sea level is 1250g per cubic meter, at what altitude is the density half of that?
The answer is 8ln(2) but I don't know why. I'd...
