Use of total head tube and mass-flow head to determine the density and velocity of a rarefied gas stream

Results are given of an experimental determination of the density and velocity of a rarefied gas stream in the range of M from 3.1 to 9.0 and of Re₁ from 45 to 1500.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 19, No. 6, pp 998–1001, December, 1970.
