If a balloon is teardrop in shape rather than spherical, the curve
would be modified so that the value of c0 , for a given Reynolds
number would be lower. In this case the sudden drop in C0
as Reynolds number increases (the change from viscous to turbulent
flow) would occur at a lower Reynolds number.
We have thus far in our discussion assumed that there is no verti-
cal motion of the air surrounding the balloon system relative to
the coordinate ! • However, this is not necessarily the case
under actual conditions. In many instances vertical llir movement is
found in the a bnosphere. Therefore, we must introduce a term to
allow for this vertical air movement. In equation (2) this term
was indicated as :tFA , the external atmospheric force.
We may consider this vertical air movEment· in terms of a velocity Dt.
Then the vertical velocity of the balloon system relative to the
air surrounding the system will be the difference between the velo-
city of the balloon relative to the absolute altitude Dt and the
velocity of the surrounding air relative to the absolute altitude
This may be equated as D~- 0 C , where Di and DC are both con-
sidered positive in the direction of increase of altitude.
The total force due to the drag, or friction will be:
FD + FATM: CD:. A ( 0!- oc>2
where the00otations are those used previously, exc.ept that now
NR = (Oz- :71 de • The relationship between NR and Co will be those
used previously.
The force due to buoyancy of the lifting gas F8 = Vb (P0 - Pg)
where:
vb: balloon volume (ft.3)
density of the air and lifting gas, respectively
(lb./ft.3)
This term my also be stated as:
where:
P0 , Pg = pressure
R0 ,Rg = specific
F
of air and lifting gas
gas constant of air and lifting
Ta, Tg : temperature of air and lifting gas
gas
The changes that will take place in this expression are those due
to a temperature difference between the lifting gas and the free
air, change in volume of the balloon due to loss of lifting gas,
change of the gas· constant of the lifting gas due to dilution with
air, and (in the case of a balloon that will hold an internal pressure)
pressure difference between lifting gas and surrounding air.
