radial width annular plates - 08/23/10 02:19 AM

In part 5.5 “annular bottom plates” – 5.5.2 there is a formula to calculate the radial width of the annular bottom plates:
At least 600 mm
215*tb/(HG)^0.5
But later on, in 5.11.2 in the second note, they refer to the minimum projection of the annular ring, with L (the greater of 450mm or Lb, not more than 0.035D).
Aren’t those 2 things the same? (With a different formula)
