## Fluid Mechanics In case of hydraulically smooth pipe, the resistance to flow depends only on the Reynolds number, whereas for a hydraulically rough pipe, the resistance to flow is governed by the relative roughness. Two pipes are said to have the same hydraulic roughness, when they have equal values of

Friction co-efficient for flows at equal Reynold number
Relative roughness
All of these
Absolute roughness

## Fluid Mechanics Select the wrong statement pertaining to flow of an incompressible fluid through a venturimeter.

Venturimeter incurs less power loss compared to an equivalent orificemeter
For frictionless flow, the fluid pressure entering the venturi meter will be exactly equal to that leaving the venturimeter
Discharge of fluid through a venturimeter depends upon the gage difference irrespective of the orientation of venturimeter
Venturimeter occupies less space than an orificemeter
