## Fluid Mechanics Velocity at a certain point in case of streamline flow is

Both A & B
Neither A nor B
Independent of time
Constant

24 mm/s
16 mm/s
12 mm/s
28 mm/s

## Fluid Mechanics In frictional fluid flow, the quantity, P/ρ + V²/2gc + gz/gc, is

None of these
Not constant along a streamline
Constant along a streamline
Increased in the direction of flow

## Fluid Mechanics With increase in the ratio of orifice diameter to pipe diameter in case of an orificemeter, the overall pressure loss

Decreases
Remains constant
Increases linearly
Increases

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

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
