A spherical balloon of 11 m in diameter is filled with helium of gas constant, R = 2.0771 kJ/kg.K at T = 15 oC and P = 100 kPa. If the balloon is used to lift load in the air of 1.25 kg/m3 density, how much load in Newtons (in addition to its own weight) can the balloon carry. Ignore drag force and weight of the balloon’s fabric? (Volume of a sphere = 4 3 ??^3 ).
