Ahydrogen-filled balloon to be used in high altitude atmosphere studies will eventually be 100 ft in diameter. at 150,000 ft, the pressure is 0.14 lb/in2 and the temperature is - 67°f. assume the balloon is spherical in shape. what is the diameter of the hydrogen balloon at the ground at 14.7 lb/in2 and 68°f
Answers: 3
as the balloom at 150,000 ft so
.
is the moment when the balloon is on the ground.
and 
.
, then 
and the radius would be ![R_2 = \sqrt[3]{\frac{3 V_2}{4 \pi}} = 11.7 \ ft](/tpl/images/0209/1893/f94a4.png)
