How much force do you have to apply to hold a helium balloon of diameter 14 cm and density ρballoon = 0.1 kg/m^3 stationary under normal atmospheric conditions. Assume the density of air is ρair = 1 kg/m^3. Give a positive answer if you have to apply an upward force and a negative answer if you have to apply a downward force. Round your answer to 3 decimal places.

Balloons are often filled with helium gas because it weighs only about one seventh of what air weighs under identical conditions. The buoyancy force, which can be expressed as Fb Pairg Vballoon. will push the balloon upward. The balloon has a diameter of 9 m Assume the density of air is ρ 116 kg/m3 and the density of helium gas to be 1/7th of this Neglect the weight of the ropes and the cage. Determine the maximum amount of Joad,...

Consider a helium balloon with volume 2.15 L. a. Calculate the buoyant force on the balloon, in newtons. Use 1.29 kg/m3 for the density of air. b. Given the mass of the rubber in the balloon is 1.65 g, what will be the net force, in newtons, in the vertical direction (taking up as positive) on the balloon if it is released? Neglect the volume of the rubber, and use 0.18×10-3 g/cm3 for the density of helium.

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 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 balloon filled with Helium (M=4g/mol) has diameter of .5m at sea level. For this problem, we'll assume a balloon can expand or contract when the outside pressure decreases or increases, so that internal pressure is always equal to the outside pressure. A) when the balloon is immersed in water to a depth of 1.5m, what is the new diameter? B) If the same balloon is released, and floats up to an elevation of 1500m (rising through air with constant...
