    Hot air balloon mass including increase in mass with balloon volume

    Hi, thank you! this is what I am looking for, I see now where I was going wrong. Thank you for the solution it is much simpler that what I was trying to do. I'll start forming by 3rd order equation right away, in order to solve it could I not differentiate it twice and find V when the equation...

    Hot air balloon mass including increase in mass with balloon volume

    Hi thanks for the response, I'm aware of Archimedes principle and that is in fact where I started for this equation. The issue comes in because the mass of the balloon is given by its volume so using Archimedes principle in its standard form does not work. I'm trying to find an equation that...

    Hot air balloon mass including increase in mass with balloon volume

    Hi sorry I realize I haven't made this very clear, I've done about 7 hours straight of work today and I'm 4 coffees in so my brain isn't working at peak performance. I know the total mass of the payload, the external temperature and pressure, the internal temperature and pressure, the density...

    Hot air balloon mass including increase in mass with balloon volume

    Hi guys, M can then be split up into 2 components: the mass of the payload which is known, and the mass of the wing. The wing material has a known thickness and density meaning its mass is given by: surface area of wing* mass per m^2 (mass m^2 is used as density and thickness are known so an...
