Presentation (12/17 at 9:00 AM)

CEE 332: Hydraulic Engineering
Spring 2005
 “The application of fluid mechanics and other science and engineering disciplines in the development of structures, projects, and systems involving water.”

Will include pipeline design, pipe network, transients, pumps, open channel flow

Design project will be a small community water supply transmission line and distribution system

CEE 452: Water Supply Engineering
Fall 2005

Analysis of contemporary threats to human health from water supplies

Criteria and standards for potable-water quality

Water-quality control theory

Design of water supply facilities


CEE 492: ESW Cornell Chapter Project:
Turbidity removal technologies for
Honduras

Organizations


Currently there are 3 distinct Environmental
Engineering M. Eng. programs at Cornell

Water Quality

Environmental Fluid Mechanics and Hydrology

Environmental and Water Resources Systems
Engineering

I am hoping to design a more flexible M.
Eng. curriculum…

Small Scale Water Treatment for
Turbid Surface Water (05-06)

Selection, evaluation, and improvement of particle removal technologies for small scale community and/or household water treatment

Collaboration with Agua Para el Pueblo in
Honduras

Will likely involve pilot scale evaluation
(lab testing)


Public Health and Water

Multiple barriers, Multiple exposures

Sedimentation/coagulation

Filtration theory

Disinfection

Creative design process

Flow control

Technology Selection

Staged Sustainable Space


Alternative coagulants

Ceramic filters

Arsenic removal

Biosand filters

Cochabamba

SODIS

Ethics of Aid

What did you learn in this course?

Each person (10 minutes)
 write down 3 to 10 things that you learned in this course

In groups of 3 or 4 (10 minutes)

Share what you learned

As a class

Each person shares their top 1 or 2 concepts

Open for comments/reflections

Collect cards


How have you used what you learned about the creative design process?

Flow Control Design Project:
Device Works…

Test it with clean water

Test it with turbid water

Plot flow rate vs. time

Report should include all design calculations and performance measurements as well as proposals for improving the device

Include photos and detailed drawings

Show in detail how this device would be used as part of a treatment process

Flow Control Design Project:
Device Fails…

Document why the device fails

Document changes you made to the device to improve its performance

Include data that shows the failure

Include design equations and analysis of the failure mode

Propose methods to improve the device or explain why this device isn’t a viable solution

Include photos and detailed drawings


It is very likely that the best ideas from the class project will be incorporated into the alum feed unit that is being design for a community in Honduras

I hope to see you often in the next days as you work on your designs!
