Tank AgitatorDesign Project

Design Goal
Design a 24/7 Wave-Like Agitation System for a TidePool Culture Tank in a Marine Biology Lab

Design Requirements - 11. Must Run
Unattended and Automatically 24 hrs/day, 7 days/wk
2. Power Sources Available 115 Vac, 15 Amp
Electricity (1725 W) 100 psig, 5 cfm
Compressed Air (1630W)
3. Gentle, Back-and-Forth Surface Agitation to Approximate Waves Breaking over an Exposed Tide Pool

Design Requirements - 24. Wave Period =
10-15 seconds5. Tank Size in feet =
2W x 3L x 1D6. Must Resist Sea
Water Corrosion7. Low Cost
$500 Budget
8. Must be Easy to Install and Uninstall (Biologists will use it) Tools Available Basic Mechanical,
Plumbing, and Wiring Hand-Tools
Hand Power Drill Reciprocating Saw
(a.k.a. SawzAll)

Design Requirements - 39. FULL Set of CAD
(AutoCAD or SolidWorks) Design and Fabrication Documents Fabrication Dwgs
for Machined Parts Material Callout
and Finish Full Dimensioning

Instructions for Assembly
Bill of Materials with Part Numbers
Electrical/Pneumatic Schematics
10.Project Management Sources of Supply
and Catalog No.s for purchased Parts

Design Requirements - 410.Project
Management cont. Projected Cost
excluding Assy Cost for Machine
Parts from Chabot Machine Tool Technology Instructors A. Long & M. Absher
Purchase Parts from Supplier Catalog or Price-Quote
11.Design Analysis & Literature Research Pros & Cons of
Alternative Designs Safe Operation
Mech. & Elect. Force Load Analysis
(statics) Corrosion Resistance Possible Failure
Modes (FMEA)

Design Requirements - 511.Extra Credit

Labor & Materials Estimates For Parts Designed
by the STUDENT, the Part-Cost will NOT be published.
Instead the Designer must solicit from Fabricators ESTIMATES or QUOTATIONS for the Cost to Fabricate the Parts
