Pipe Areas

[Lordkro]

Hi,

I need to calculate the formulas of a certain pipe section that consists of a shell and a branch (see image below):



The areas are demarcated with hatching and named: A_{fs I}, A_{fb I}, A_{fb II}, A_{fs II}, A_{p I}, A_{p II}

The basic Formulae are pretty easy to get to, with regards to just splitting the area members in different shapes, like for instance A_{fb I}:

A_{fb I} = (L x B) + (0.5 x b x H)
Where this is easy to see that the shape members are a rectangle and a triangle(with a 90 degree angle inside)

What I am struggling to determine is the individual items which will have their own formulae, like for instance B = e_as = d_o - d_i

Anyone willing to help please do.

Thank you in advance!

This looks like a "commercial" but tedious and long problem.

I suggest go to the nearest university or community college and hire a hungry "graduate" engineering student to calculate those numbers.
