Primerjava metod za določevanje gostote gostote zraka pri kalibraciji uteži

Novak, Brigita (author), Cvetko, Dean (mentor), Grgić, Goran (co-mentor)

V svoji diplomski nalogi sem testirala različne metode za določanje gostote zraka pri določanju mase uteži. Na primerjalnih meritvah referenčnih uteži sem preučila primernost dveh metod, ki se običajno uporabljata v laboratoriju: CIPM enačbo ter njeno poenostavljeno obliko. Moji izsledki kažejo, da je v okviru pričakovanih napak poenostavljena oblika zveze, ki določa maso uteži s popravkom vzgona iz meritev zraka, dovolj dober približek za uporabo v referenčnem laboratoriju.

• Title: Determining air density during calibration of weights

Abstract

In my thesis I tested different methods of determining air density, when measuring the mass of a weight. Using comperative measurements of different weights, I studied the effectiveness of two methods that are normally used in a mass laboratory: CIPM formula and its approximation formula. My results show that within the expected diviations the approximated CIPM method is adequate and may be used for the referencing laboratory purpose.
