This increases the reliability of extrapolation to higher temperatures. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. I’m remembering now given two sets of T,v you can solve the constants and plot a curve in the T,v plane which is not a straight line and read off any value you want.
It’s easy to join and it’s free. The constant was allowed to vary in charts published after By joining you are opting in to receive e-mail. The general relationship is: Adjunct DViscosity-Temperature Charts 1—73 1.
You could build a table: Thanks for sharing your spreadsheet. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. It is provided for convenience in connection with reports and data evaluation. But, the log log needed for this equation isn’t working 3d41. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The only problem is the axes are not v and T. Plotting Viscosity Data and making the ASTM D Graph Logarithms actually if you look more carefully you will notice that the horizontal scale is a log scale in K, but usually values are shown in degrees C and the vertical scale is a loglog scale.
An American National Standard Designation: The ASTM d chart uses this scale.

Register now while it’s still free! The improved charts given here utilize even different scale ratios for dimensional convenience and a different constant 0. Then to read the scale you wouldn’t look at each gridline and then at the legend to figure out the values associated with the gridlines.

This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years d3411 if not revised, either reapproved or withdrawn. The kinematic viscosity and temperature scales were not made to the same ratios in Test Method D — This form can also be used to calculate the temperature associated with a desired kinematic viscosity.
This standard has been approved for use by agencies of the Department of Defense.
