__FLUID MECHANICS__

**COURSE OBJECTIVES:**

• To introduce the students about properties and
behaviour of the fluids under static conditions and to impart basic knowledge
of the dynamics of fluids through the control volume approach and to expose to
the applications of the conservation laws to a) flow measurements b) flow
through pipes (both laminar and turbulent) and c) forces on pipe bends with an
exposure to the significance of boundary layer theory and its applications.

behaviour in static conditions.

**CO2
**Apply
the conservation laws applicable to fluids and its application through fluid
kinematics and dynamics.

**CO3**
Formulate the relationship among the parameters involved in the given fluid
phenomenon and to predict the performance of prototypes by model studies.

Estimate the losses in pipelines for both laminar and turbulent conditions and
analysis of pipes connected in series and parallel.

**CO5**
Explain the concept of boundary layer and its application to find the drag
force excreted by the fluid on the flat solid surface.
