Recentes mutationes in AWWA signa habent confusio inducitur ad notiones factoris designationis (DF) et factoris salutis (SF).

Hoc documentum necessitudinem declarabit inter duos terminos

• AWWA signa referens

• Dum mensam exemplorum

Design factor defined

AWWA C900, C905, et signa C909 define "consilium factor" ut sequitur:

"Design Factor (DF): inversus salus factor. Ponitur ad reducere fundamentum hydrostaticum in consilio (HDB) ad perveniant ad Design Hydrostatic Accentus (HDS) ex quibus Pressura Classis est ratione. "

Hanc definitionem in simpliciora verba ponens:

Design Factor (DF): Inversus the salus factor. DF reducere accentus materiales fractionis providendum est tulo consilio lacus.

In forma aequationis:

Design accentus = Breaking accentus x DF

or * *

HDS = HDB x DF

Relatione factor et design SALUS FACTOR

AWWA definitio clarissima est: the consiliorum factor est inversus factor salutis.

Iterum in aequatione forma;

DF = 1/SF

or * *

SF = 1/DF

CONSTANS SALUS PARS 2.0

A binis columnis in tabula ultimis, it Constat AWWA constanter servasse maximum factorem 0,50 (aequivalent) ad minimum elementum salus 2.0).

Uni-Bella commendat fabrum conservare the practice of using 2.0 as the minimum safety factor for design.
