Checking back in on this thread.
We went from applied physics to astroglide. For the record, I think we’ve generally remained on topic, when you think about it.

Re: Physical Oceanography/Applied Physics
I love Google, it’s a crutch for tired memory. I knew there was a simple calc for dynamic pressure of water based on velocity. Very short form example is 69.5 psi is the dynamic pressure of water at 70 mph. So, if you jump out of a car on the freeway into a lake, you’ll see a pressure spike of 69.5 psi assuming you don’t hit pavement first and slow down. I learned this in nuke school with pump laws. Note the relationship is NOT linear, it’s a square function for velocity vs pressure. 35 mph (1/2) drops the pressure by 4 times or 17 psi and change. Going the other way, 140 mph (double the original speed) you go up in pressure by 2 squared or four for a dynamic pressure of about 280 psi.
How fast do you want to go? And will you care what time it is when you hit?

And to bring it all home, how can Astroglide help my wrist achieve 35 mph (17 psi) while I'm showering and will the watch (and me) still function after?Henryj wrote: ↑Wed Sep 19, 2018 5:28 amI love Google, it’s a crutch for tired memory.

Edit: According to this G force calculator if the watch were to go in one direction at 35 mph, and then suddenly reverse direction at 35mph over the course of 1 second, my watch would achieve 3.2 G's in the shower.

3.2 g from 35 mph to 0? That’s a bit over 16 meters.

Re: Physical Oceanography/Applied Physics
Anywaaaaaayy,
Static pressure at 300 meters is about 441 psi. Add the 25% for wet testing as a dive watch and we see 551 psi as a static test pressure. Even if you’re a hood ornament on a 688, you could safely go to test depth at a flank bell and the watch would be fine, but I doubt even Paul would volunteer to be the test dummy for that little caper.

You might need to worry about banging against rocks, heads, sand, random hard bits, but you won’t see any of the giant mythological pressure spikes from water that WUS desk divers get all a-flutter about.Grahamcombat wrote: ↑Wed Sep 19, 2018 7:00 amMy initial thoughts were relating to surf zone and shore break and the force endured in that tumble smash.Henryj wrote:Anywaaaaaayy,
