Water (μ=0.001kgm⋅s)is flowing through a 3-mm diameter, 9-m
long horizontal pipe steadily at 0.6m/s. Determine the regime of
flow and solve the pressure drop and head loss through the
pipe.
A certain liquid flows in a 10mm diameter smooth pipe that is
20m long. The total head loss in the pipe is 30m and the Reynold's
Number is 1800. Calculate the Darcy-Weisbach friction factor,
volumetric flowrate, and kinematic viscosity. (Board Exam
