Method for determining pressure drop of monatomic gases flowing in turbulent motion through constant-area passages with simultaneous friction and heat addition

Charts are presented that enable convenient determination of the pressure drop sustained by monatomic gases (ratio of specific heats, five-thirds) flowing at high subsonic speeds in a constant-area passage under the simultaneous influence of friction and heat addition. Although the charts are constructed for determining pressure drops when heat is added at constant passage-wall temperature, pressure drops can be determined with good accuracy for other modes of heat addition through the use of an effective wall temperature in conjunction with these charts.
