Analysis of laboratory beating by fiber settling time frequency distributions.Application: Statistical analysis of fiber settling is a new approach for measuring the degree of refining refining, any of various processes for separating impurities from crude or semifinished materials. It includes the finer processes of metallurgy, the fractional distillation of petroleum into its commercial products, and the purifying of cane, beet, and maple sugar . In samples of hardwood hardwood: see wood. hardwood Timber obtained from broad-leaved, flower-bearing trees. Hardwood trees are deciduous trees, except in the warmest regions. kraft pulp beaten in the laboratory to different extents, fiber populations were studied with respect to how the fibers settle in a cylinder of water. Results showed that the mean fiber settling times The introduction to this article provides insufficient context for those unfamiliar with the subject matter.

You can discuss the issue on the talk page. increased from 34.4 s for a beating time of 5 min to 69.9 s for a beating time of 50 min. A similar increase was observed in the standard deviations In statistics, the average amount a number varies from the average number in a series of numbers. (statistics) standard deviation - (SD) A measure of the range of values in a set of numbers. in frequency distributions of fiber settling times-from 11.3 s for 5 min of beating to 33.7 s for 50 min of beating. On average, with the increase in beating time, the fibers settled more slowly, and the spread of settling velocities was greater. Regression correlations were developed to elucidate e·lu·ci·date v. e·lu·ci·dat·ed, e·lu·ci·dat·ing, e·lu·ci·dates v.tr. To make clear or plain, especially by explanation; clarify. v.intr. To give an explanation that serves to clarify. the relationships between beating time and mean fiber settling time and between beating time and the standard deviation of frequency distribution. There was a good fit for the experimental data. H. R. Ghatak is with the Chemical Technology Dept at S.L.I.E.T., Longowal-148 106, Punjab, India. Email Ghatak at h_r_ghatak@yahoo.com |
