Real fluid properties of normal and parahydrogen

Computer program calculates the real fluid properties of normal or parahydrogen using a library of single function calls without initial estimates. Accurate transport and thermodynamic properties of molecular hydrogen are needed for advanced propulsion systems

NACA Technical Notes

Report presenting a time-temperature parameter based on examination of the published stress-rupture data for a variety of materials, rather than on physical theory, is presented in equation form. An examination of published data on 40 materials representing ferritic and sustenitic steels, high-temperature alloys, and aluminum alloys is used to create conclusions
