But, the log log needed for this equation isn’t working out.

ASTM D – 17 Standard Practice for Viscosity-Temperature Charts for Liquid Petroleum Products

Download Now Defense manufacturing is all about project manufacturing and project accounting. Extrapolations into such regions from lower temperatures will lack accuracy, however. Ashm purposes of extrapolation, it is especially important that the two known kinematic viscosity-temperature points be far apart. With computers that seems like the easy way.

Last previous edition approved in as D —93 The improved charts given here utilize even different scale ratios for dimensional convenience and a different constant 0. Then if you a simple excel linear plot Y vs X or log log excel plot based on Y1 d3341 X1 I think you would have a straight line on your graph slope 1 on the linear plot.

We need your help!

The Eng-Tips staff will check this out and take appropriate action. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Labeling those gridlines would be the challenge. Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.

Seven charts are available as follows: Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Reliable data can be usefully plotted in the high temperature region even if astj does exhibit some curvature. By joining you are opting in to receive e-mail. This increases the reliability of extrapolation to higher temperatures.

An American National Standard Designation: This test method details the standard procedure for plotting viscosity-temperature charts that ascertain the kinematic viscosity of a petroleum oil or liquid hydrocarbon at any temperature within a limited range, provided that the kinematic viscosities at two temperatures are known. Current edition approved Dec.

You could take out all auto-generated gridlines and tickmarks and build your own vertical gridlines using extra series with constant values of T and your own horizontal gridlines with constant values of v. The constants A and B can be evaluated for s341 fluid from two data points.

Draw a sharply defined straight line through them. ASTM International takes no position respecting the validity of any aetm rights asserted in connection with any item mentioned in this standard. aatm

Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. I sure appreciate the help. We need your help astn maintenance this website. These are necessary when calculations involve kinematic viscosities smaller than 2. This form can also be used to calculate the temperature associated with a desired kinematic viscosity.

Adjunct DViscosity-Temperature Charts 1—73 1. Red Flag This Post Please let us know here why this post is inappropriate. It should be noted that this value is not the value of B given in Eq X1. Plotting Viscosity Data and making the ASTM D Graph Logarithms actually if you look more carefully you will notice that the horizontal scale v341 a log scale in K, but usually values are shown in degrees C and the vertical scale is a loglog scale.
