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.
