Question

A uniform pipeline, 5000 m long, 200 mm in
diameter and roughness size (ε) 0.03 mm, conveys water at
15 oC (ν = 1.13x10-6 m2/s) between two reservoirs, the
difference in water level is maintained at 50 m. In addition to
the entry loss of 0.5v2/2g and an exit loss k = 1.0. Determine the steady discharge between reservoirs using
a. Colebrook-White equation
b. Explicit function of f
