Calculations: Using the relationship given, obtain the friction factor for each pipe, calculate Re for each flow rate and plotf vs Re. Compare the constructed plot with that on the Moody chart given. Establish relative roughness for each pipe and the absolute roughness of pipes. Compare with values given on the Moody Chart. Comment on effect of roughness and pipe diameter on pressure drop in the system.

The friction factor has been correlated with two properties of the piping system: Reynolds number & roughness of the pipe surface. This relationship is presented on the Moody Chart (attached). The objectives of this exercise are: To determine the friction factor at various flow rates, obtain the roughness of pipes and compare them with published values. To plot the data to compare how closely the experimental data agrees with the given chart. To observe and comment on the effects of pipe surface roughness and pipe diameter on pressure drop within a system, which are important in the design of process piping systems 15 3 fazo 5 10 DI 11 12 16 13 16 Diagram Key 1.
