Question:

Use Fig. 10.14, Table 10.3, and Table 10.4 (in §10.6) to assess the following statements as true or false:

In Figure 10.14

In table 10.3

In table 10.4

a. If k_s/D is 0.05 or larger, and the flow is turbulent, the value of f is not dependent on ReD.
b. For smooth pipes and turbulent flow, f depends on k_s/D and not ReD.
c. For laminar flow, f is always given by f = 64/ReD.
d. If ReD = 2 × 10⁷ and k_s/D = 0.00005, then f = 0.012.
e. If ReD = 1000 and the pipe is smooth, f =0.04.
f. The sand roughness height k_s for wrought iron is 0.002 mm.
