【Abstract】 This article discusses the way of measuring the air flow of compr- essors I-100/8 and 4L-20/8 by means of Pitot tube. It also discusses the location and installation of Pitot tube and introduces the way to determine the average flow rate from the central flow rate inside a pipe measured by the Pitot tube.更多还原
