Prototyping, Engineering Analysis, Simulation

We 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 plates.

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 Down

In 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.
