BT3402	FLUID FLOW AND HEAT TRANSFER OPERATIONS	LTPC

3003

COURSE OBJECTIVES:

• To introduce the students the mechanics of fluids through a thorough understanding of the properties of the fluids, behaviour of fluids under static conditions. The dynamics of fluids is introduced through the control volume approach which gives an integrated understanding of the transport of mass, momentum and energy.
• 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 vanes.
