Objectives

This course aims to acquaint students with the principles of conservation of mass, motion quantity in fluid flow, various situations on the field of mechanics engineering, namely in pipe flow (shear and turbulent), pump performance and centrifugal fan, fundamental quantity measurement, exterior flow and notions of incompressible flow.

This course lasts a semester and it is a complementary course of Fluid Mechanics I (1st Semester)
