Empirical equations were developed giving minimum air and power requirements for the vacuum and pressure transport of crushed coal through vertical pipelines. Data used in the development were obtained from transport tests in a 50-foot vertical 6-inch-diameter pipeline and in a system of 2-, 4-, 6-, and 8-inch-diameter horizontal pipelines, each preceded by a short vertical run. The air and power requirements are dependent upon coal rate and specific gravity, upon pipe diameter and length, and upon the ratio of cross- sectional area of the coal pickup section to the pipe.
