Apparatus fabrication and air density measurement
英文摘要
An apparatus for measuring air density was fabricated ,which could simultaneously test and show four air parameters ,temperature ,humidity ,pressure and density .T he four air parameters of enclosed air were measured by the apparatus ,and the ideal gas state equation was well proved by the results .The uncertainty of the obtained air density was 0 .1 kg/cm3 .It was found that the uncer-tainty of the humidity had the most impact on the error of air density measurement .
