How to calculate buoyancy?
I’ve been looking at the hundreds of formulas in this Wikipedia page but I have no idea which one is appropriate.
Basically I want to calculate how much air is needed to bring a person back to the surface after it is submerged.
Let’s say a person wearing only a wetsuit dives to 10 or 15m and then inflates an air bladder with a CO2 cartridge.
I’d like to know how much air is needed or what is the force needed to bring that person back to the surface? How do I calculate that?
I’d appreciate any thoughts or calculations that can help me with this.
Anyone willing to help me out?
Thanks in advance!
