2 Final Exam, 8AM May 7, Will cover entire course 155 Fitzpatrick Around half on material since last midterm Like 1.5 midterms in length Multiple choice Free answer writing Free answer calculator problems Will provide separate information packet for use in exam: graphs, tables, etc. Bring all formula sheets Question Session: Saturday, DB 207, 5:30PM
3 Course Topics 1. Pumps, Turbines and Pipe networks Moment of Momentum Revisited Types of pumps and turbines and uses Pump-pipe systems, networks 2. Open Channel Flow Specific Energy and Rapid Transitions Hydraulic Jumps Slowly varying flow Open channel control structures 3. Introduction to Surface Water Hydrology Hydrologic Cycle Rainfall, Runoff and Design Events 4. Hydraulic Structures Dams, weirs, spillways Effects of Hydraulic Structures
4 Pumps, Turbines and Pipe Types of Machines Networks Moment of Momentum: Pump or Turbine? Centrifugal Pumps Simplified Theory Pump Selection Pump-Pipe Systems Intersection of Pump Curves and System Curves Cavitation
5 Pumps Continued Dimensionless groups Head rise coefficient Power coefficient (shaft power) Flow coefficient (discharge) Efficiency (linearly related to other three) Specific Speed and type of machine Types of pumps and turbines Wind Turbines Pipe Networks: Hardy Cross Method
6 Open Channel Flow Types of Flow Uniform Gradually Varying Rapidly Varying Speed of Small Disturbances Froude Number Supercritical, Critical, Subcritical Flow
7 Open Channel Flow Cont. Specific Energy!!! Variation in energy, depth Combined with Bernoulli s equation Minimum energy and super/subcritical lobes Width changes, flow rate changes Broad-Crested Weirs Sharp-Crested Weirs Underflow Gates Hydraulic Jumps
8 Open Channel Flow Cont. Uniform Channel Flow Balance between gravity and friction Manning s equation Compute Flow Rate Compute Depth Compute Slope Compound Channels Design of Lined and Unlined Channels
9 Open Channel Flow Cont. Gradually Varying Flow Friction slope: Manning s equation Depth Changes with distance Normal Depth Actual Depth Critical Depth Flow Profiles Critical Points and their importance
10 Hydrology Hydrologic Cycle: Important Processes Watersheds Units! Runoff and SCS Methods Curve Numbers: Flow Chart and TR-55 Manual Composite Watersheds Situations not in the Tables Incremental Runoff with Time
