Say I want to send a helium balloon into the sky. For all intents and purposes this balloon is circular, with volume V. I will fill it with helium to the same pressure as the air outside it (I assume that this is important). The weight of the balloon and the payload is W.
So, I assume I have to calculate the weight of the helium + balloon, and, somehow, the weight of the air that the balloon replaces. So if the helium and the balloon is g grams lighter than the air would be, then I have g grams of lift?
And how would I go about converting g grams of lift to meters per second?
If anyone can help me out with some ways to calculate this, I would be very grateful. If there are important variables that I have left out, I certainly would appreciate that being pointed out aswell.
