Prerequisite: CE 35000.

Textbook: Hwang, N.-H.C. and Houghtalen, R.J. (1996). Fundamentals of Hydraulic
Engineering Systems, 3rd Ed., Prentice-Hall, Inc., Upper Saddle River, NJ.

Coordinator: Reza M. Khanbilvardi, Professor of Civil Engineering.

Objectives: The aim of this course is to give Civil Engineering majors a basic understanding of flow systems in closed and open hydraulic systems. This course is designed to provide detail computation for studying, analyzing and design of components of hydraulic systems such as pipes, pumps and open channels. Included in this course will be experimental works which help students to learn and visualize different hydraulic phenomena in a laboratory environment.

Prerequisites by topic:

  1. Fluid Properties.
  2. Fluid Statics.
  3. Pressure Variation in Flowing Fluids.
  4. Buoyancy.
  5. Momentum and Energy Equations.

Topics:

  1. Principle of Conservation of Mass, Energy and Momentum.
  2. Losses in Pipes. Friction and Local Losses in Pipe Elbows and Valves (Also Lab: Pipe Flow Experiment).
  3. Pipes in Series and Parallel. Pipe Systems.
  4. Equivalent Pipes. Pipe Network Analysis.
  5. Laminar and Turbulent Flow. Boundary Layers.
  6. Velocity Distribution in Pipes (Also Lab: Laser Experiment)
  7. Reservoirs.
  8. Pumps.
  9. Pumps in Parallel and Series (Also Project: Pumping System Design).
  10. Open Channel Flow. Specific Energy, Losses. Critical, Supercritical and Subcritical Flow.
  11. Weir Flow. Orifice Flow (Also Lab: Hydraulic Bench Experiment).
  12. Steady-State Flow. Hydraulic Jumps. Hydraulic drop.
  13. Uniform Flow. Mannings Equation (Also Lab: Open Channel Flow Experiment).
  14. Non-Uniform Flow. Gradually Varied Flow Equation. Water Surface Profiles.

Class/Laboratory Schedule: 2 Lect., 3 Lab.;hr./wk; 3 cr.

Computer Usage:

  1. One required homework assignment. Develop a program to solve Standard Step and Direct Step Methods in open channel non-uniform conditions.
  2. One required software in measuring flow velocities in closed conduit with the help of Laser.

Laboratory Projects:

(Including major items of equipment and instrumentation used):

  1. Measurement of friction loss in pipe flow.
  2. Measurement of velocity distribution in pipe using Laser Doppler Anemometer.
  3. Calibration of rectangular and triangular weirs using a hydraulic bench.
  4. Measurement of critical and normal depth in open channel flow.

Design Project: About 1/3 of this course is designed to produce guidelines and methodologies to design hydraulic system which includes pipes and pumps. For example, students are given a scenario in which certain flow rate has to be provided from a reservoir to a higher elevation community. They have to select from at least four different size pumps and appropriate combination system with a designed pipe system to be sufficient. This process includes decisions on the hydraulic system, efficiency consideration, and cost estimation.

Estimated ABET Category Content:
