Summary of Model Parameters, Assumptions, and Relevant Formulae used in Scaling the Simulated Vomiting Device.

Assumptions: (1) Flow through the human esophagus and machine esophagus was treated as flow through a smooth pipe. (2) In some cases, the machine dimensions were rounded to the nearest available dimension offered by material manufacturers. (3) The vomitus fluid inside the human body will be the same inside the vomiting machine; achieved by using surrogate vomitus with similar viscosities.
