04: A balloon initially deflected and flat is connected by a valve to a tank containing helium gas at (1MPa) at ambient temperature (20°C). The valve is now opened, and the balloon is inflated at constant pressure (equal to ambient pressure 100 kPa) until it becomes spherical at (D₁=2m). This balloon is to be inflated slowly to the final diameter of (4m), at which point the pressure inside is (400 kPa). All temperature remains at (20°C) during the process. Determine the minimum volume of the helium tank to inflate this balloon? Ans.(22.34 m³)
