### ME2204 FLUID MECHANICS AND MACHINERY Syllabus for Mechanical Third(3rd) Semester - Anna University

 ME2204 FLUID MECHANICS AND MACHINERY L T  P C (Common to Aeronautical, Mechanical, Automobile & Production) 3  1 0  4

OBJECTIVES

·    Th student   is  introduce t th mechanics  of  fluids  throug  thorough understanding of the properties of the fluids. The dynamics of fluids is introduced through the control volume approach which gives an integrated under standing of the transport of mass, momentum and energy.
·    The  applications  of  the  conservation  laws  to  flow  though  pipes  and  hydraulics machines are studied
