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

Venturimeter occupies less space than an orificemeter
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
