Problem 25P
(II) A spherical balloon has a radius of 7.15 m and is filled with helium. How large a cargo cai it lift, assuming that the skin and structure of the balloon have a mass of 930 kg? Neglect the buoyant force on the cargo volume itself.
ANSWER:
Solution 25P:
We have to calculate the maximum mass of the cargo that the balloon can lift from the given problem statement.
Step 1 of 4
Concept:
Archimedes Principle: The buoyant force acting on the balloon placed in air of density is equal the weight of the air displaced by the volume of the balloon. Mathematically,
