|Title:||STUDIES ON PIPELINE TRANSPORTATION OF SOLID WASTES|
|Abstract:||The present investigation pertains to. the studies of flow behaviour of sludge from a recovery section of a paper mill. The experimental set - up consisted of G.I. Pipe ( I.D. = 27.9 mm) and plastic pipe (I.D. = 46.0 mm). The concentration of sludge used for the study was 30 %, 25 %, 20 %, 15 %, 10 %, 5 % by weight of solids. The sludge was found to exhibit Bingham - plastic behaviour. Based on experimental studies the following correlation for laminar turbulent - transition velocity has been recommended. (NRe)C = 87.6 (NHe)0.48 Different correlations for pressure drop. have been proposed for the flow of sludge through G.I. and plastic pipe lines. These correlations include the rheological properties of the sludge. The correlations are valid for the following range of parameters. NRe = 3 x 102 to 2 x 10 4 (G.I. pipe) NRe = 6 x 102 to 3 x 10 4 (Plastic pipe) NHe = 2 x 102 to 2 x 104|
