Empirical equations were developed giving minimum air and power requirements for the vacuum and pressure transport of crushed coal through horizontal pipelines. The test system included 2-, 4-, 6-, and 8-inch-diameter pipelines, each with a 200-foot straight section followed by three shorter runs connected by 90 deg bends of different radii. Air requirements were found to be a function of coal rate and specific gravity, pipe diameter and length, and the ratio of the cross-sectional area of the pickup section to that of the pipe.
