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