[PSUBS-MAILIST] Assistance needed, anyone please!

[via Personal_Submersibles]

After many years and many hospital holidays, 🙂 I am no longer a financial member.

However, I am hoping that someone may assist me in the spirit of  Psubs.

If memory serves, there was a calc formula on your site of which I no longer have access .

Any way, I have a project idea that to continue with, relies on the minimum weight achievable for the following ;

 

A 2 meter diameter sphere with appropriate bracing material and with safety margins 

To dive to sea-water safe depth of 150meter (160psi) No doors No windows 

Windows and doors will add much I know, however, are details to be considered later only if the basic weight indication makes the project viable.

So basically, I need to know the framing and sheeting steel sizes and thicknesses to calculate the overall weight in this basic form. If positive at such point I will apply for re- membership to follow through with my idea.

I know this sounds vague and I am asking much, but could someone assist me in this very basic task, which I know not how to do. 

Thanking any member who might be inclined to assist me. 

Cheers Les  

Safe diving 🙂
