What is payload of Balloon ?

Payload of a Balloon if defined as maximum mass which a Balloon can carry with in it upward direction.


"V" is the volume of Balloon 

d_out : is the density of out side air

d_in: is the density of gas inside of Balloon.

m:  is Maas of Balloon is m then

Payload= [d_out×V]- [d-in×(V+m)]

Illustrative Example :

(2) A balloon of diameter 20 m weighs 100 kg. Calculate its paylod if it is filled with helium at 1.0 atm and 27 ∘ C. Density of air is 1.2 kg m −3 .(R=0.082 dm 3 atm K −1 mol −1 ).
