Hank,
I take it a 1" thick 60" diameter sphere weighs 4521 lbs leaving 2509 lbs of positive boyancy.
A 1.25" thick 60" diameter sphere weighs 5650lbs leaving 1380 lbs of positive boyancy. Are my calcs correct? Anyone know how much pressure these can withstand?
My thought is 3300 feet is 1470psi. With a higher than 1.25 safety factor I should aim for 2,000 psi or more. Right?
Thanks,
Scott Waters
