WebSo to lift a person, say, 72 KG, you'd need a bit over 12 KG of helium, but that's a lot of helium. And, it may seem strange that 10 KG can lift 60 KG, but it's like holding a balloon under water. A balloon - which weighs very little in the air has significant lift in water because it's much lighter than the water surrounding it. Web5 mei 2024 · We can now simplify Equation 1 greatly: V = m payload ρ − P M h R T = m payload P M a R T − P M h R T. Giving that. (2) V = m payload R T P ( M a − M h). This equation, Equation 2, is superior to Equation 1. We now only need the temperature and pressure at an altitude in order to calculate the volume of the balloon.
