dcterms:description
The use of hydraulic transport during the extraction of nodules from the seabed will need constant monitoring of speed and concentration of solid grains in a vertical pipeline. In that case the most important is the measurement in the begin part of the pipeline exposed to high pressure and high flow nonstationarity. On the basis of this submission, the authors have built a prototype of a measuring device which tests on laboratory piping are the subject of the article. The presented research we conducted during transport of the nodules’ ceramic models in a vertical pipeline with an internal diameter of 150 mm, under conditions of non-stationary flow, expected during operation offshore, and the results we compared with radiotracer measurements and recorded the head losses at the measuring section of the pipeline.
