To adjust the values in Table 8.3.1.3 for different Hazen-Williams C values, you should use factors from which table?

• A. Table 8.3.2.2
• B. Table 7.8.1
• C. Table 8.1.4
• D. Table 8.3.3

Answer: (A)

Adjusting for different Hazen-Williams C values uses a table of correction factors dedicated to C. In NFPA 14, the values in Table 8.3.1.3 are modified by multiplying (or applying the specified adjustment) with factors from Table 8.3.2.2, which provides the C-value correction factors. This directly accounts for how pipe roughness (C) changes the friction loss or related values in 8.3.1.3. The other tables cover different topics and do not supply the C-factor adjustments needed here. So the table used for these adjustments is Table 8.3.2.2.
