How do I find the accelerating ascension rate of my helium balloon?
Ignore factors such as the increase of volume as it ascends, temperature, wind etc.
I just want the basic ascension rate of ideal non changing conditions.
rho_f Outside air density - I think typical air density is this - 1.2 kg/m^3
v Volume - 179.59438 m^3
m Mass - 90.7184 kg
g Earth's gravity - 9.80665 m/s^2
Through some research I have been given this formula but am not sure if its the correct one or how to compute it.
a = g*(rho_f * V - m)/(rho_f*V + m)
