    Resid viscosity determination

    Hi, jmw You don't have to answer my previous question. I calculated the viscosities outside of your model using your formula and got the answers I needed. They are pretty close to my earlier calculations. Thanks a lot! tchitz

    Resid viscosity determination

    Hi, jmw thanks a lot! How do I increase the width of the columns? How do I change the scale of the Y axis?

    Resid viscosity determination

    Thanks! The assay has the viscosity at higher temperatures such as 250. However, The model I am using needs an input of viscosity at 122 oF. What I did was back calculate the 1025 + viscosity from the 650+ and the whole crude viscosities. I've arrived at similar answers using both but I'm...

    Resid viscosity determination

    Lab results of assay of particlar crude I am analyzing does not include viscosity at 122oF of the resid, i.e, 1025+ cut. What is the best way to determine the implied viscosity of the 1025+ resid @ 122oF? Viscosity @ 122 oF of different cuts from 374 oF to 1025, whole crude, and 650+ are...
