Fluid Mechanics Select the wrong statement pertaining to flow of an incompressible fluid through a venturimeter. Venturimeter occupies less space than an 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 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 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 ANSWER DOWNLOAD EXAMIANS APP
