    What is the ascension rate of a gas balloon without air friction?

    How do I find the ascension rate of a gas balloon when you factor in air drag? Its inflated Not partially inflated from release. I have calculated that my gas balloon's ascension rate is 13.49031149 m/s^2 from initial release WITHOUT air drag. Ignore wind and let's say ground air density...

    Phrak is correct and the balloon is Inflated.

    What is the ascension rate of a gas balloon without air friction?

    I have calculated that my gas balloon's ascension rate is 13.49031149 m/s^2 WITHOUT air friction. Ignore wind and let's say ground air density is 1.2 kg/m^3 at 20 °C. The shape of the balloon will be a cylinder with rounded ends. The top end will have a 4 meter diameter so the area of that is...

    Undergrad Calculating Ascension Rate of a Helium Balloon

    How would I find the constant non accelerating ascent due to air friction? haha

    Undergrad Calculating Ascension Rate of a Helium Balloon

    So if I did this correctly the answer is: 13.490311 m/s^2 ?

    Undergrad Calculating Ascension Rate of a Helium Balloon

    How do I find the accelerating ascension rate of my helium balloon? Ignore factors such as the increase of volume as it ascends, temperature, wind etc. I just want the basic ascension rate of ideal non changing conditions. rho_f Outside air density - I think typical air density is this - 1.2...
