A spherical balloon filled with helium gas must lift a1.00-kg scientific payload off the ground, and the mass of the empty balloon is 0.500 kg. The mass densities are 1.286 kg/m3 for air, 0.179 kg/m3for helium gas, 1.251 kg/m3 for nitrogen gas. Part A What is the minimum diameter of the balloon? Express your answer with the appropriate units. d = SubmitMy AnswersGive Up Part B A helium shortage forces the scientists to consider using nitrogen gas in the balloon....
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 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 spherical balloon has a radius of 6.15 m and is filled with helium (pie- 0.179kg/m3). How large a cargo can it lift when such a balloon is in the air (Pair 1.29kg/m3), if the skin and structure of the balloon have a mass of 650 kg? Assume that there is no buoyant force on the volume of the cargo.
How many helium-filled balloons would it take to lift a person? Assume the person has a mass of 69 kg and that each helium-filled balloon is spherical with a diameter of 33 cm.
A helium balloon (in the shape of a sphere) has radius 7.10 m . For the density of air, please use 1.29 kg/m^3, and for Helium, use .179 kg/m^3 Part A How much additional mass (payload) could this balloon lift? You should assume the balloon's skin, plus other parts of the balloon's structure have a total mass of 930 kg Note however that this number does NOT yet include the mass of the helium filling the balloon, which you will...
A helium balloon floats still at an altitude of 1.39 km. The balloon has a spherical shape with a diameter of 11.0 m, and its skin and structure has a mass of 311.5 kg. a.) What is the absolute pressure at this altitude? Assume a constant density for air. b.) Calculate the buoyant force the air exerts on the balloon. c.) How much cargo can the balloon carry, in kg?
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)
balloon A helium balloon ride lifts up passengers in a basket. Assume the density of air is 1.28 kg/m3 and the density of helium in the balloon is 0.18 kg/m3. The radius of the balloon (when filled) is R = 5.4 m. The total mass of the empty balloon and basket is mb = 121 kg and the total volume is Vb = 0.062 m3. Assume the average person that gets into the balloon has a mass mp = 72...
