Fluid Mechanics Two fluids are flowing through two similar pipes of the same diameter. The Reynold's number is same. For the same flow rate if the viscosity of a fluid is reduced to half the value of the first fluid, the pressure drop will Decrease Remain unchanged Data insufficient to predict relative pressure drop Increase Decrease Remain unchanged Data insufficient to predict relative pressure drop Increase ANSWER DOWNLOAD EXAMIANS APP

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