Abstract

Local priissure losses for Sodium Carboxymethyl Cellulose (SCMC), aqueous solutions in pipe-fittings were experimentally measured, for concentrations range from 0.03 to 1.1 wt.%. Pressure drop-flow rate relation has shown similar behaviour, (power expression), to that of pipe flow with the same power. Correlations were predicted for the evaluation of press-ure drop in different pipe- fittings, which enable to estimate the local losses for another pseudoplastic fluids if the behaviour equations are found.
