Project Staffing ME1:
Fluid analysis test section, inputs, outputs
Design any flow straightener
Select pump system ME2:
Design test specimen mount
Design/analyze 4 test specimens
Assist with structure
ME3: Design structure of
tunnel and supports Design drainage system Design structure for
transporting EE1:
Work with ME1 designing electronic controls for pump
Power supply Controls input and
output on display
Customer Feedback (me) If it can show
streamlines over different shapes, project successful
House of quality shows all tests useful/necessary and customer needs captured
All metrics are attainable if given appropriate budget

Possible Future Projects/Uses Demos in class Lab experiments Develop new test
specimens Add pressure taps
and force sensors on test specimens
Mount camera and use computer for pathline tracking
