A spherical hot-air balloon is initially filled with air at 120 kPa and 20°C with an initial diameter of 5 m. Air enters this balloon at 120 kPaand 20°C with a velocity of 3 m/s through a 1-m-diameter opening. How many minutes will it take to inflate this balloon to a 16.50-mdiameter when the pressure and temperature of the air in the balloon remain the same as the air entering the balloon? The gasconstant of air is R = 0. 287 kPa m³/kg K. (Round the final answer to three decimal places.)Getty ImagesThe time it takes to inflate the balloon ismin.
