Two approaches:
1. Describing the detailed flow pattern at
every point in the field
2. Control Volume method
Working with finite region, making a
balance of flow in and flow out; and
determining gross flow effects

fluid is at rest or moving in such a
way that there is no relative motion

concerns with the variation of
pressure throughout a fluid and the
effect of pressure on submerged
Buoyancy, Flotation,
and Stability
Buoyant force the resultant force
acting on a body that is completely
submerged or floating in a fluid
Archimedes principle
the
buoyant force has a magnitude
equal to the weight of the fluid
displaced by the body and is
FLUID PRESSURE
Concerns to Explore:
1. Pressure at a Point
2. Variation of Pressure from Point to
Point
3. Pressure Measurement
Pascals law (Blaise Pascal)
The pressure at a point in a
fluid at rest, or in motion, is
independent of direction as long
