The air-release flap on a hot-air balloon

Reference no: EM13552523

The air-release flap on a hot-air balloon is used to release hot air from the balloon when appropriate. On one hot-air balloon, the air release openings has an area of 0.5 m^2, and the filling opening has an area of 1 m^2. During a two minute adiabatic flight maneuver, hot air enters the balloon at 100 kPA and 35 degrees C with a velocity of 2m/s; the air in the balloon remains 100 kPa and 35 degress C; and air leaves the balloon through the air-release flap at velocity 1 m/s. At the start of this maneuver, the volume of the balloon is 75 m^3. Determine the final volume of the balloon and work produced by the air inside the balloon as it expands the balloon skin.
