Learning Outcomes
Upon frequenting and passing the subject, the students should know how to:
(A) identify the thermophysical properties of fluids (chap. 1)
(B) determine the pressure distribution of a fluid at rest or in rigid body motion (chap. 2)
(C) apply the conservation laws to fluid dynamics problems (chap. 3)
(D) use dimensional analysis to simplify the complexity of a problem and highlight the relevant physical ratios (chap.4)
(E) analyse internal flows to determine duct diameters, head losses and flow rates (chap.5)
(F) identify the structure of the flow near a rigid wall and analyse boundary-layer flows over simple geometries
