47.
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.
Discharge of fluid through a venturimeter depends upon the gage difference irrespective of the orientation of venturimeter.
Venturimeter occupies less space than an orificemeter.
Venturimeter incurs less power loss compared to an equivalent orificemeter.
