A spherical balloon is 50 ft in diameter and surrounded by air at 60 F and 29.92 in Hg abs. (a) if the balloon is filled with hydrogen at temp of 70 F and atmospheric pressure, what total load can it lift. (b) if it contains helium instead of hydrogen, what load can it lift (lbf) if gravitational acceleration is 31.85 ft/s2?
