How to relate internal pressure and weight?
(OP)
Dear fellows,
Please someone correct me if I'm wrong. In appendix F "internal pressure cannot exceed the weight of the roof".
So:
Pi (kN) < Wr (kN)
-> Wr is a known value (ton);
-> Internal pressure is limited to 3kPa;
-> Di is the inside diameter of the tank (m);
Dp < Wr
pi*Di^2/4*Dp < Wr*9,81
Then, "internal pressure cannot exceed the weight of the roof plus the weight of the shell".
So:
pi*Di^2/4*Dp < (Wr+Ws)*9,81
Thanks in advance

I appreciate your comment, but I am aware of all of it. I simply wanted to know if my calculations were right. Please, correct me if I'm wrong. Thank you.

In the second equation, wr would include the weight of rafters supported by the shell as well.

I suppose "weight of plate/square meter", the "square meter" is pi*ID^2/4. Am I right?
