Engineering Analysis of Integrated Components

This spreadsheet analyzes the theoretical air flow from the pump. Investigation of theoretical differential pressure calculations due to venturi tube design and losses due to the system tube design. Assumptions for this analysis are included in the table below. The following charts describe the expected flow relationships based on the venturi tube analysis, Flow vs. Differential Pressure and Flow vs. Input Voltage to Pump. These plots are both described with an expected exponential relationship.

Risk Assessment

The following has been revised from original risk assessment completed 4/10/13. This revision converges on the technical risks present in our detailed design for the Portable Emergency Ventilator. Further, we have narrowed the project operational risks evaluated on 4/10/13 and minimized the risk associated with each item.
