Determination de la masse volumique de l'air

Abstract

Weapplied in thisworktwoexperimentalmethods for determining the density of air, the practice of the twomethodsis made in working conditions for studyparameters of temperature and relative humidity. Westudied in this practice the comparisonbetween the method by contemplation of a water displacementgas and that of Boyle and Mariotte and the effect of thesetwoparameters (T, Hr) on the measurementresult the density of air. The measurementresults in thisstudy show that the volume of air masses obtained by the twomethods are almostidentical in the sameworking conditions. In the end wepresented a comparisonbetween the measured values and standard values, the comparison gave verysimilar and comparable values with minimal gaps and almostnegligible in the order of 1/100 [g/〖cm〗^3]. In addition, the temperature has an effect on the density of air the latter operates in a counter direction to that of the temperature.
