We consider a hot-air balloon of mass 269 kg (basket and envelope). The spherical envelope of the balloon has a diameter of 15 m when fully inflated. To what temperature in °C) must the enclosed air be heated for the balloon to carry three standard men? Assume the surrounding air is at 20°C and is treated as an ideal gas. Use 29 g/mol for the molar mass of air. (Assume the mass of each standard man is 70 kg.) 97.45...

We consider a hot-air balloon of mass 231 kg (basket and envelope). The spherical envelope of the balloon has a diameter of 15 m when fully inflated. To what temperature (in °C) must the enclosed air be heated for the balloon to carry five standard men? Assume the surrounding air is at 20°C and is treated as an ideal gas. Use 29 g/mol for the molar mass of air. (Assume the mass of each standard man is 70 kg.)

A hot air balloon consists of a basket hanging beneath a large envelope filled with hot air. A typical hot air balloon has a total mass of 529 kg, including passengers in its basket, and holds 2.59 X 10 m of hot air in its envelope. If the ambient air density is 1.26 kg/m?, determine the density (in kg/m) of hot air inside the envelope when the balloon is neutrally buoyant. Neglect the volume of air displaced by the basket...

A recreational (open) hot air spherical balloon has a radius of 7.30 m when fully inflated. The total weight of the balloon, basket, ballast and pilot is 1710 N. When the balloon is released from its mooring, it moves upward and reached a terminal velocity of VT = 0.910 m/s. If the air resistance is given by Fair resistance = b VTwhere b = 2570 kg/s, what is the density in the hot air in the balloon? The density of...

b. A hot air balloon has a volume of 2000 m3 when fully inflated, and the air inside the balloon is always at atmospheric pressure because of the large opening used to fill the balloon and heat the air inside it. What's the mass of hot air inside the balloon if its temperature is 120°C? (Assume a molecular weight of 28.8 g/mole for air.) 1790 kg 5850 kg 62.0 kg 203 kg

A recreational (open) hot air balloon (i.e., Pinside ≈ Poutside has a volume of 2339m3 when fully inflated. The total weight of the balloon body, basket, ballast and pilot is 1950.2N (439lb). How much less dense must the air in the balloon be than the surrounding atmosphere in order to keep the balloon floating level near the ground? (That is, give the difference of the densities.) Thank you for your help

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 = 4.8 m. The total mass of the empty balloon and basket is mb = 120 kg and the total volume is Vb = 0.068 m3. Assume the average person that gets into the balloon has a mass mp = 71 kg...
