Problem:
How to calculate CODAP Isolated opening, Shell stress verification, Nozzle values l , S , and St?
- I = 70.546 mm
- S = 1239.3 mm^2
- St = 2456.6 mm^2
Solution:
Given the following information:
Output report:
Code Reference: Figure C5.1.4b10
Solve for l:
As indicated in Figure C5.1.4 b10, lt (available length of branch) is measured along the nozzle wall. When the nozzle is mounted on a formed head, the available branch length may be greater than the nozzle projection.
Using Figure C5.1.4b10 and C5.1.4b11, solve for S and St
Solve for S:
S = (L + et - et) * e
S = (199.596 + 20.4 - 98.5) * 10.2
S = 1239.3 mm^2
Solve for St:
St = (et * l) + (et * e)
St = (20.4 * 70.546) + (98.5 * 10.3)
St = 2456.6 mm^2
