    The Calculation of Viscosity Blending Indices Using the Refutas Equation

    . The following equation for calculating the Viscosity Blending Index (VBI) of heavy oils is often referred to as the Refutas method and I have seen it published in the technical literature in both of the forms below: VBI = 14.534 × ln[ln(v + 0.8)] + 10.975 VBI = 14.534 × log[log(v + 0.8)] +...

    Standard reference conditions for gas flow in ISO-10780

    Does anyone have a copy of ISO-10780 "Stationary Emissions - Measurement of Velocity and Volume Flow Rate of Gas in Ducts" ?? If you do: (1) I believe the standard reference conditions for gas volumes in that standard is 20 °C (293 °K) and 101.325 kPa ... is that correct? Is there also a...

    Does ASME have any reference conditions for expressing gas volumes?

    Does ASME have any standard reference conditions of temperature and pressure for expressing gas volumes? In one of their flowmeter test or design procedures? Or in any of their standards? If they do have such conditions, what are they? And what is the title of the publication or standard or...
