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...
5. A very large hot air balloon and its accompanying structure (i.e. the basket, rigging, equipment, etc) have a mass of 400 kg. The air inside the balloon must be heated to a temperature of 200 OC for the balloon to lift off the ground when the outside air temperature is 16.0OC. To what temperature must the air be heated if the balloon is to lift off with three 80.0-kg people aboard? Note: Problem 5 requires three pictures of the...
