Pipes were installed aboveground at the federal Bureau of Mines Morgantown Energy Research Center, Morgantown, West Virginia, To develop and evaluate different types of systems--vacuum or pressurized, horizontal or vertical--and to obtain information for the design and operation of a practical system. This paper presents the results of experiments in the vacuum horizontal transport of up to 2 1/2-inch coal through 2-, 4-, 6-, and 8-inch-diameter pipelines. Minimum air rates required to move the coal in full suspension and pressure losses resulting therefrom were related to coal and pipe variables in the form of empirical equations that were used in predicting minimum power requirements.
