Abstract The ASME Pressure-Viscosity Report was a seminal publication on high pressure-viscosity and density supervised by the ASME Research Committee on Lubrication, sponsored by dozens of industries, and undertaken by Harvard University using high-pressure equipment developed by Prof. P. W. Bridgman. The resulting measurements of the “Viscosity and Density of Over 40 Lubricating Fluids of Known Composition at Pressures to 150,000 psi (1034 MPa) and Temperatures to 425 °F (218.3 °C/491.5 K)” should have become an invaluable reference to tribologists around the world. The present work revisits that monumental effort to distill the results into an established equation of state using modern computer software. The authors used curve-fitting techniques to fit measured density and viscosity data to the parameters of the Tait-Doolittle equation for use in further tribological modeling. This information will help a new generation of engineers to model the piezoviscous properties of lubricant base-stocks in diverse tribological applications.

Design Margin

The ASME Section VIII Division 3 Pressure Vessel Design Code adopted in its 2004 edition a significant change of the design margin against plastic collapse. There are several reasons and justifications for this code change, in particular the comparison with design margins used for high pressure equipment in Europe. Also, the ASME Pressure Vessel Code books themselves are not always consistent with respect to design margin. This paper discusses not only the background material for the code change, but also gives some practical information on when pressure vessels could be designed to a thinner wall.
