Course Description
  1. Flow in pressurized pipes: Fundamental equations of hydraulics.
  2. Calculation of energy losses in pressurized pipes: friction (major) losses, local (minor) losses, equivalent pipe length.
  3. Energy grade line and hydraulic grade line.
  4. Pipes in series, pipes in parallel, branched pipe systems supplying reservoirs.
  5. Design of pressurized pipe systems, hydraulic machines (pumps and turbines).
  6. Open-channel flow: definitions, pressure distribution, specific energy, types of flow.
  7. Flow control. Computation of the water free-surface profile along open channels and flow control sections (constrictions and drops).
  8. Specific force (momentum function). Momentum theorem. Hydraulic jump (energy losses in the jump, types of jumps, jump length).
  9. Resistance equations for steady flow.
  10. Uniform flow in open channels, normal flow depth, calculation of hydraulic and geometric characteristics of open channels. Fundamental equations of open-channel hydraulics.
  11. Cross-section optimization (hydraulically optimal cross-section).
  12. Gradually varied flow, classification of free-surface profiles, computation of water surface profiles.
  13. Outflow. Weirs. Types of weirs (sharp-crested and broad-crested). Analysis of different weir types (rectangular, triangular, etc.). Sluice gates.
  14. Flow from a reservoir into an open channel. Effect of a downstream reservoir on the operation of a connecting channel with an upstream reservoir.
  15. Laboratory exercises.
