Flow of Water Through Condenser Tubes

Abstract

Abstract In this paper the authors give particulars regarding an extended series of tests recently conducted at the United States Naval Engineering Experiment Station at Annapolis, Md., to determine the friction loss of water flowing through ⅝-in. No. 18 gage standard condenser tubes. The investigations covered variable velocities, water temperatures, and tube lengths, as well as the effect of both fresh and salt water. The results obtained are presented in tabular form and from them a general formula has been derived which gives the total drop in pressure due to entrance and exit losses and to frictional resistance within the tube.
