Description |
This teaching unit focuses on elementary notions of urban hydraulics, mainly applied to sewer systems. Free surface flows is teached in W05. This unit focuses on pressurized flows. They give the basis for TU W43. Textbook: - Finnemore E.J and Franzini J.B. Fluid mechanics with engineering applications, 10th edition, McGraw Hill, 2002, NY.; and - Handouts. |
