In an experimental setup for a pipe flow, velocity is measured at two different points. Point 1 is 1 cm away and point 2 is 2 cm away from the pipe wall. If the increase in the velocity from point 1 co point 2 is 16%, estimate the roughness t: for the pipe surface.

A 2-m-wide and 1-m-high rectangular conduit of concrete (t: = 2 mm) is used co supply water to a town population by gravity. To meet the supply requirement, the flow rate is required to be 8000 gal/min. Determine the inclination of the conduit to meet this requirement.
