About 20 years ago I held onto a boat anchor and let it carry me to the bottom of a shallow lake. I unintentionally learned the burst pressure of my inner ear. I could feel liquid inside my ear and couldn't hear clearly for weeks. 😕
Followup information from one of the original HabHub creators: "Re: ascent rate. Here are the ascent rate profiles for 3 identical flights (same payload, balloon and fill) - as you can see they are pretty different. Identical Flights (www.flickr.com/photos/16828840@N07/sets/72157668632631187) I think unless you can predict which profile your going to get your probably better off not over-complicating the modeling. Re: scale height vs air density model - your correct it's similar. But the air density model value is empirically derived from balloon data and includes factors like the constraining effect of the latex envelope."
All the questions answered.

Am looking into a building (un-manned) helium/electric engine hybrid craft, just for fun. Thx!
Good luck
@@SciJoy Thx! I wish graphene baloons were standard. Off I would go! They wouldn't leak that expensive helium either.
Did you build it?

The identical Flights link didn't come out

She is just cute .. rest are calculations
😂😂😂😂oh freakk!!
