MINIMIZING THE PRESSURE GRADIENTS IN CAPSULE PIPELINES

The pressure gradients due to cylindrical capsules were reduced by up to 80% by providing them with plastic instead of steel surfaces or by fitting them with collars. The power requirements of a capsule pipeline depend greatly on the capsule density, and if the capsules were constructed so that a third of the volume consisted of voids, the power needed to transport two teragrammes (2 million tons)/year of solid with a density of 1500 kg/cu.m (s.g. = 1.50) in A 254 mm (10 in.) pipeline would be reduced by over 90%. The pressure gradients and power required to transport spherical capsules were generally much smaller than those required for even the smoothest cylinders of the same specific gravity. /Author/TRRL/
