Here's my understanding...
(P1V1)/T1 = (P2V2)/T2
P1 = starting pressure, typically sea level pressure which is 1atm.
V1 = Starting volume of the gas inside your balloon.
T1 = starting temperature, temperature at ground level.
P2 = final pressure, this should be the pressure at your flight altitude.
V2 = final volume, should be 100% of balloon capacity.
T2 = final temperature, temp at flight altitude.
Now I'm trying to understand this from a lighter than air gas standpoint, so...
Do i assume that:
P1, T1 are what i stated above, and do i assume that P2, T2 are proportional, if the gas isn't heated by a secondary source such as a hot air balloon?
Thanks in advance, will post further questions once these are validated or corrected!
