Heat Transfer and Pressure Drop for Turbulent Flow of Air-Water Mixtures in a Horizontal Pipe

The static pressure drop and heat transfer for two-phase, two-component flow of air and water were measured for flow in a horizontal 15-ft length of 1-in. 16-gage brass tubing. Flow rates include the range of 1000 to 15,000 lb per hr for the water and 0 to 200 lb per hr for the air. Tentative correlations are presented from which prediction of pressure drop and heat transfer may be made under restricted flow conditions.
