Determine what diameter should the spherical balloon have

Reference no: EM13310347

A balloon is to be used to carry meteorological instruments to an elevation of 15,000 ft where the air pressure is 8.1 psia. The balloon is to be filled with helium, and the material from which it is to be fabricated weighs 0.01 lbf/ft^2. If the instruments weigh 8 lbf, what diameter should the spherical balloon have?
