Week 9 Subsystem Design ReportsClick the links below to view our reports from Week 9. These reports present our work from the Subsystem Design phase, including feasibility analyses, benchmarking research, design concepts, design decision making processes, preliminary drawings, risk assessments, preliminary bills of material, and budget considerations.
Prototyping, Engineering Analysis, SimulationWe have developed several spreadsheets relating to our feasibility analyses that can be used as handy calculators.
The Fluid Model Calculator computes the flow rate and time it would take for a fluid to exit our hopper, based on hopper height and cross-sectional area.
The Hopper COG Calculator computes the
location of the center of gravity for our hopper based on
its dimensions and the volume of particles inside.
The Paschen Breakdown Calculator uses
Paschen's Law to compute the voltage needed to create an
arc flash at a given distance between two charged
The Receptacle Size and Screw RPM
Calculator computes two parameters relevant to
the design of our recirculation system: the size of the
receptacle required for the manual recirculation concept
to be feasible, and the RPM required for the screw
conveyor concept to be feasible.

Requirement Flow DownIn the Detailed Design phase, it is essential to keep the original Customer Requirements (CRs) and Engineering Requirements (ERs) in mind. To that end, we created a document that details the relationships between the components of our subsystems and the high-level CRs and ERs. Click the link below to view this document.
