Selecting the Filling Balance Weight
The proper filling balance weight depends on the weight of the
payload (radiosonde and possible extra equipment) and the weight and
shape of the balloon. The proper filling balance weight can be found
using the curves on Figure 2 and information in Table 4.
Figure 2 illustrates the estimated bursting altitudes for balloons of
different weight, material, and carrying different payloads. For
example, when a 200 g TA balloon is loaded with a Vaisala
radiosonde, the estimated bursting altitude for the balloon is in 21
kilometers.

Balloon Bursting Altitude
To achieve the rate of ascent of 320 m/min, the required nozzle lift is
determined according to Table 4. For example, for Vaisala
Radiosonde (300 g) lifted by a 200 g balloon, the required nozzle lift
is 790 g.
