      The aim of this research is to find general empirical equations for predicting drag coefficient and settling velocity (for polymeric system of Car boxy Methyl cellulose CMC and Hydroxyl Ethel cellulose HEC as non-Newtonian fluids and water as Newtonian fluid), and to compare these equations with the other equations in literatures to show the accuracy of the developed equations.Empirical equation was found to relate drag coefficient C and Reynolds number Rep for a wide range of Repd from 0.001 to 10000 and for spherical and irregular shaped particles for Newtonian and non-Newtonian fluids as follows:
