Pressure-drop versus flow-rate data were taken on water (room temperature) flowing in a 30.0 m section of old 1-inch Schedule 40 pipe (Table 1.7). Calculate the friction factor versus the Reynolds number for these data. How do the results compare to the standard correlation for the friction factor (i.e., the Colebrook equation)? Be quantitative. If we assume that there has been some scaling (i.e., deposition of hard deposits on the inner walls) that has decreased the effective pipe ID, can we improve the correspondence between the data and the literature correlation? Discuss.
