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

For frictionless flow, the fluid pressure entering the venturi meter will be exactly equal to that leaving the venturimeter

Venturimeter incurs less power loss compared to an equivalent orificemeter

Venturimeter occupies less space than an orificemeter

Discharge of fluid through a venturimeter depends upon the gage difference irrespective of the orientation of venturimeter
