Design Meeting Minutes
Summer 2009 Minutes
7/3/2009
Accomplishments
- Worked on midterm wiki report
- Changed baffle function so that floc tanks draw faster
Floc Hopper Group
Accomplishments
- Finished writing the MtoA code that will create the floc hopper for the plant.
- Updated the wiki page to include pictures of the floc hopper and its dimensions.
- Updated files in the Final Design folder (floc hopper - new design, floc hopper - old design, and replaced a link in the Master Program to call our new floc hopper file)
Issues
- Need to change the origin of our floc hopper in the code so that it will be placed correctly within the plant.
Goals for upcoming week
- Will work on placing the floc hopper in the correct position in the plant, as well as testing the floc hopper with various plant sizes.
Floc Tank Group
Accomplishments
- Number of baffles in the last channel is now even
- Designed prototype for flocculator drainage system that requires no valves and drew in AutoCAD
Issues
- Subtracting a single baffle seems to have added more channels for smaller plant flow rates than anticipated
- The ports between the channels take up the entire height of the tank for certain flow rates
Goals for upcoming week
- Compare and understand the effect of removing a single baffle in the last channel to the original design
- Ensure that the baffle spacing is no smaller than the width of the ports
- Draw slots to slide the baffles into
- Send drainage design to engineers in Honduras to review
Materials List Group
Accomplishments
- Worked on editing/improving wiki page for Final Midterm report
- Added more calculations to MathCAD file including weir pipes, sed plate frame, and chimneys
- Updated wiki page with all calculations
- Created Input and Output tabs on Variable Naming Guide for the Materials List and loaded file to the wiki
Issues
- Figuring out the most efficient and helpful way to organize our data and calculations
- Had trouble understanding drop chimney dimensions - Demonstration at team meeting was helpful
Goals for upcoming week
- Finalize materials
- Price components
