We present a wide-ranging correlation expressed in terms of temperature and density for the viscosity of ethanol based on critically evaluated experimental data. The correlation is designed to be used with an existing equation of state from the triple
Annually since 1997, the U.S. Department of Commerce (DOC) provides a report to the Office of Management and Budget (OMB) summarizing federal agency use of government unique standards (GUS) used in lieu of voluntary consensus standards (VCS) during the
Digital Twin has become an important technology for advanced manufacturing. However, to ensure that digital twins provide valuable decision support, the results generated by the digital twins must be trustworthy for real manufacturing systems. Model
