Measurement of the Universal Gas Constant Using an Acoustic Resonator
Competition is a great motivator. The 1988 measurement of the universal gas constant R at NIST [1] was stimulated by an error made at a rival national metrology institute, Great Britain’s National Physical Laboratory (NPL). In 1976, a group at NPL reported a “new” value for the universal gas constant R that had a standard uncertainty of 8.4 ppm (1 ppm = 1 part in 10). The “new” value was 159 pp...
متن کاملMeasurement of Complex Permittivity using Planar Resonator sensor
A Microstrip loop resonator sensor designed to determine the dielectric constant of a liquid is proposed. The resonator sensor designed for 1GHZ for different structure of loop is described. The sensor is implemented using planar microstrip technology. A dielectric material is placed above microstrip ring resonator. As a consequence the near field of the resonator interacts with the material un...

متن کاملhazard evaluation of gas condensate stabilization and dehydration unit of parsian gas refinery using hazop procedures
شناسایی مخاطرات در واحد 400 پالایشگاه گاز پارسیان. در این پروزه با بکارگیری از تکنیک hazop به شناسا یی مخاطرات ، انحرافات ممکن و در صورت لزوم ارایه راهکارهای مناسب جهت افزایش ایمنی فرا یند پرداخته میگردد. شرایط عملیاتی مخاطره آمیز نظیر فشار و دمای بالا و وجود ترکیبات مختلف سمی و قابل انفجار در واحدهای پالایش گاز، ضرورت توجه به موارد ایمنی در این چنین واحدهایی را مشخص می سازد. مطالعه hazop یک ر...
Gas Sensor with Electroacoustically Coupled Resonator
Abstract A new configuration for a gas sensor is demonstrated. The configuration consists of an electroacoustic element coupled to an acoustic resonator, such as Kundt’s tube, exhibiting a resonance frequency that is related to the velocity of sound, which, in turn, is a function of the molecular mass of the gas within the resonator. Electrical impedance measurements were performed, whereby a r...
