The discharge from an old sewer 400 m long when flowing full has been measured as 40 Vs. The pipe diameter is 200 mm and has an estimated surface Head Lost roughness of 0.6 mm. Taking the kinematic viscosity as 1.0 mm /s, calculate the head loss in the pipe. (the non- dimensional friction factor 2-0.02; g is taken as 9.81 m/s?)
