The following table provides four sets of Fanning friction factor data, for different values of Reynolds number (Re) and roughness factor k/D. Which of the above sets of friction factor data is correct?

Set	f	Re = 102		Re = 103		Re = 105
		k/D = 0	k/D = 0.001	k/D = 0	k/D = 0.001
Set I	f	0.16	0.016	16×10−5	16×10−5
Set II	f	0.016	0.16	0.0055	0.0045
Set III	f	0.16	0.016	0.0045	0.0055
Set IV	f	0.0045	0.0055	0.016	0.16
