Payload is defined as the difference between the mass of displaced air – InterviewSolution

1.	Payload is defined as the difference between the mass of displaced airand the mass of the balloon. Calculate the pay load when a balloon ofradius 10 m, mass 100 kg is filled with helium at 1.66 bar at 27°C.(Density of air = 1.2 kg m–3and R = 0.083 bar dm3K–1mol–1).
Answer» Pay load is defined as the difference between the mass of displaced air and the mass of the balloon. Calculate the pay load when a balloon of radius 10 m, mass 100 kg is filled with helium at 1.66 bar at 27°C. (Density of air = 1.2 kg m^–³ and R = 0.083 bar dm³ K^–¹ mol^–¹).
