Calculations on U235 Fission Product Decay Chains

Calculations on U235 Fission Product Decay Chains

Date: May 1952
Creator: Faller, I. L.
Description: Report of equations for calculating decay of U235. The introduction states" Calculations have been made on the U235 fission product decay schemes. The results for a typical example, that of a reactor operating at 1000 kilowatts for 180 days, have been tabulated and graphed. General formulae have been used so that the results can be applied for any power level and any time of irradiation" (p. 2).

NBS Viscometer Calibrating Liquids and Capillary Tube Viscometers

NBS Viscometer Calibrating Liquids and Capillary Tube Viscometers

Date: December 26, 1962
Creator: Hardy, R. C.
Description: Report discussing measurements of viscosity made with relative viscometers. These instruments must be calibrated with liquids whose viscosities are known. NBS provides a series of 10 oils for this purpose. Their viscosities range from 0.02 to 450 poises and their temperature coefficients of viscosity range from 2.1 to 9.4 percent per degree C. The less viscous oils are more stable. Correction formulas for errors or conditions are presented.

International Practical Temperature Scale of 1948: Text Revision of 1960

International Practical Temperature Scale of 1948: Text Revision of 1960

Date: September 8, 1961
Creator: Stimson, H. F.
Description: Report is a text revision of the International Temperature Scale of 1948; the numerical values of temperatures remain the same. The adjective "Practical" was added to the name by the International Committee on Weights and Measures. The scale continues to be based upon six fixed and reproducible equilibrium temperatures to which values have been assigned, and upon the same interpolation formulas relating temperatures to the indications of specified measuring instruments. Some changes have been made in the text to make the scale more reproducible than its predecessor. The triple point of water, with the value 0.01 ºC replaces the former ice point as a defining fixed point of the scale. It is also recommended that the zinc point, with the value 419.505 ºC, be used instead of the sulfur point. The recommendations include new information that has become available since 1948.

Formulas, Tables and Curves for Computing the Mutual Inductance of Two Coaxial Circles

Formulas, Tables and Curves for Computing the Mutual Inductance of Two Coaxial Circles

Date: August 5, 1924
Creator: Curtis, Harvey L. & Sparks, C. Matilda
Description: Scientific paper issued by the Bureau of Standards over the mutual inductance of two coaxial circles. As stated in the abstract, "a number of examples are given to show the methods of computation by the different formulas, tables, and charts" (p. 541). This paper includes tables, and illustrations.
