Balloons are often filled with helium gas because it weighs only about one seventh of what...
To know how many Helium balloons are needed to lift a girl who weighs 35 kg, one intends to measure how much weight a single balloon can lift. A scale that is sensitive to 0.1 g, small pieces of copper, and an ordinary party balloon show that a balloon with a volume of about 2 l can lift 2g of copper. How many balloons will it take to lift the girl? Does this agree with the result obtained if you...
A large weather balloon whose mass is 222 kg is filled with helium gas until its volume is 322 m3. Assume the density of air is 1.20 kg/m3 and the density of helium is 0.179 kg/m3. (a) Calculate the buoyant force acting on the balloon. 3786.72 N (b) Find the net force on the balloon. N upward (c) What additional mass can the balloon support in equilibrium? kg Please help!
A large balloon of mass 226 kg is filled with helium gas until its volume is 325 m3. Assume the density of air is 1.20 kg/m3 and the density of helium is 0.179 kg/m3. (a) Calculate the buoyant force acting on the balloon. (b) Find the net force on the balloon and determine whether the balloon will rise or fall after it is released. (c) What maximum additional mass can the balloon support in equilibrium? (d) If you skip (c),...
A spherical balloon has a radius of 7.65 m and is filled with helium. The density of helium is 0.179 kg/m3, and the density of air is 1.29 kg/m3. The skin and structure of the balloon has a mass of 930 kg . Neglect the buoyant force on the cargo volume itself. Determine the largest mass of cargo the balloon can lift.

A spherically shaped balloon has a radius of 10.5 m, and is filled with helium. How much extra mass can a cargo lift, assuming that the skin and the cargo of the balloon have a mass of 1200 kg? Neglect the buoyant force on the cargo volume itself.(The density of air is 1.29 kg/m3 and the density of helium is 0.179 kg/m3).
A spherically shaped balloon has a radius of 13 m, and is filled with helium. How much extra mass can a cargo lift, assuming that the skin and the cargo of the balloon have a mass of 1000 kg? Neglect the buoyant force on the cargo volume itself.(The density of air is 1.29 kg/m3 and the density of helium is 0.179 kg/m3)
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 ).
A blimp is cruising slowly at low altitude, filled as usual with helium gas. Its maximum useful payload, including crew and cargo, is 1.52E+3 kg. The volume of the helium-filled interior space is 5.51E+3 m3. The density of helium gas is 0.16 kg/m3, and the density of hydrogen is 0.081 kg/m3. How much more payload could the blimp carry if you replaced the helium with hydrogen?
