## Hydraulics & Fluid Mechanics A bucket of water is hanging from a spring balance. An iron piece is suspended into water without touching sides of bucket from another support. The spring balance reading will

remain same
increase/decrease depending on depth of immersion
increase
decrease

## Hydraulics & Fluid Mechanics Two dimensional flow occurs when

the fluid particles move in plane or parallel planes and the streamline pat-terns are identical in each plane
the velocity of successive fluid par-ticles, at any point, is the same at suc-cessive periods of time
the magnitude and direction of the velocity do not change from point to point in the fluid
the direction and magnitude of the velocity at all points are identical

## Hydraulics & Fluid Mechanics A fluid is said to be ideal, if it is

inviscous
inviscous and incompressible
incompressible
inviscous and compressible

## Hydraulics & Fluid Mechanics Non uniform flow occurs when

the velocity of successive fluid par-ticles, at any point, is the same at suc-cessive periods of time
the direction and magnitude of the velocity at all points are identical
velocity, depth, pressure, etc. change from point to point in the fluid flow
the fluid particles move in plane or parallel planes and the streamline pat-terns are identical in each plane
