Validación de nuevo modelo degradiente de presión en el hidrotransporte laminar de pulpa laterítica.

In the present work a study is carried out to validate a new pressure gradient model using a semi-industrial hydrotransport facility, with the use of crude lateritic slurry at a temperature of 27 °C and a concentration of solids by weight of 41,93%. Pressure drop experiments were carried out in a straight section of horizontal pipe in order to validate the model. As main results, a new theoretical pressure gradient model is obtained for cylindrical and horizontal pipes, in laminar flow regime, with a Herschel-Bulkley rheological behavior of the fluid; the error percentage does not exceed 0,98%, being more precise taking as reference the results reported in technical literature.
