The Effect of the Condensation of Atmospheric Water Vapour on Total Head and other Measurements in the N.P.L. High Speed Tunnels Note on the Interpretation of Readings of Pitot and Static Tubes in a High Speed Tunnel in which Condensation ofnMoisture is Taking Place

摘要

To investigate total-head losses and previously unexplained inconsistencies in pitot traverse drag measurements in the existing high-speed tunnels at the National Physical Laboratory, and the disadvantages of using humid air in high-speed tunnels generally.
