so here it is, I want to build a sphere with pressure being exerted uniformly on all sides. the sphere will be immersed in a fluid and have mass pumped out(to create buoyancy.) I have calculated the strength of the sphere to be...(adsbygoogle = window.adsbygoogle || []).push({});

C=((Pw-Pi)r)/2T

where

Pw=Pressure of the Water

Pi=Internal Pressure

r=radius of sphere

T=the thickness of the spherical skin

Buoyancy is given by a separate equation.

What I would like to know is "if the diameter of the sphere is off uniform(is built by humans) what strength is required by the sphere. I haven't ever done calculations on error ranges and I do not know where to look to learn about how to do it. Learning how would be much more helpful than just knowing this case, but I will accept either!

Thanks in advance
