This book was released on 2014-02 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The measurement of the physical properties (density, viscosity, surface tension, thermal conductivity, etc.) is of great importance to the research, industry and physical, chemical and biomedical applications. The thermal conductivity is a measurement of the material's ability to conduct heat. The Transient Hot Wire method is a suitable method to measure the thermal conductivity due to its very cheap cost of construction, accuracy and because it is a fast method of measurement. The implementation requires accurate temperature sensing, automatic control, data acquisition and data analysis. The basic procedure consists of measuring the temporal temperature rise in a thermoresistance (thin wire) immersed in the solution by applying an electrical current in the wire. Therefore, the wire works as a heat source and a temperature sensor. The time of measurement is very short and therefore the convection effect could be minimized. Then, the heat transfer to the infinite medium is due only to the conduction transfer effect. The thermal conductivity can be determined from the slope of the curve T versus ln(t) due to the linear relation between T and ln(t)."

Book Synopsis Guidelines for Evaluating and Expressing the Uncertainty of NIST Measurement Results (rev. Ed. ) by : Barry N. Taylor
Download or read book Guidelines for Evaluating and Expressing the Uncertainty of NIST Measurement Results (rev. Ed. ) written by Barry N. Taylor and published by DIANE Publishing. This book was released on 2009-11 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of measurements and conclusions derived from them constitute much of the technical information produced by the National Institute of Standards and Technology (NIST). In July 1992 the Director of NIST appointed an Ad Hoc Committee on Uncertainty Statements and charged it with recommending a policy on this important topic. The Committee concluded that the CIPM approach could be used to provide quantitative expression of measurement that would satisfy NIST¿s customers¿ requirements. NIST initially published a Technical Note on this issue in Jan. 1993. This 1994 edition addresses the most important questions raised by recipients concerning some of the points it addressed and some it did not. Illustrations.

Book Synopsis Thermal Conductivity of Refractories by : P. Jeschke
Download or read book Thermal Conductivity of Refractories written by P. Jeschke and published by . This book was released on 1978 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The German Standard Deutsche Industrie Norm (DIN) 51046 covers the measurement of thermal conductivity of refractories up to 1600°C by the hotwire method. From the publishing of the first draft in 1969 to issuing the standard in 1976, several round-robin tests and other experimental work have shown that 1. the hot-wire method is safe to use for material up to K = 2 W/m * K, and under certain precautions may be used up to K = 6 W/m * K, 2. the simplified solution of the Fourier differential equation used in the standard can be safely applied if the thermal diffusivity is smaller than a = 0.002 m2/h, 3. for material with a > 0.002 m2/h, the recommended measuring time has to be reduced. 4. several recommendations can be given about the type of furnace and measuring equipment and suggestions can be made on how to avoid errors, and 5. the hot-wire method produces consistently higher values for thermal conductivity than other methods, including the ASTM procedure.
