The effect of sanding on the roughness statistics of the unfiltered profiles. (Error bars represent the 95% confidence limits for the precision uncertainty.)
Grahic Jump Location
Overall frictional resistance coefficient versus Reynolds number for all the specimens. (Precision uncertainty ≤±0.3% at all Reynolds numbers; overall precision and bias ranges from ±1.4% at highest Reynolds number to ±4.8% at lowest Reynolds number.)
