دانلود کتاب Comprehensive Volume and Capacity Measurements

In this work, the most recent available data has been used in respect of density of water and mercury. Latest temperature scale namely, ITS 90 has been used. All possible permutation and combinations of influence parameters like coefficient of expansion, density of standard weights used, and reference temperatures have been used in preparing corrections/factors tables. The book contains 14 chapters. It is for the first time that concept of solid base primary standard of volume has been discussed. Various standards of volume and capacity, starting from solid base primary standard down to field standards, have been detailed. The chapters 1 and 2 also include realization, hierarchy, traceability, periods of verification, and maximum permissible errors of various standards. Precautions and recording of data using gravimetric/volumetric methods have been described. Step by step methods of calibration of volumetric measures have been discussed. Volumetric glassware from one microlitre upward has been dealt with in detail. Design, fabrication, and calibration of standard capacity measuring from 10 millilitres to 5,000 litres have been discussed. Verification methods of high capacity storage tanks of various shapes and orientation, including ships and barges of a few thousand cubic-metres is one of the firsts of the book. Separate chapters on vehicle tanks carrying petroleum, edible liquids, and likes have been presented. Design and fabrication of large capacity measures to be used as standards have also been dealt with. The range of measurement covered is from one micro litre to several million litres.
