A rheological study of guar gum indicated a non-Newtonian, pseudoplastic behaviour of its solutions. When the data was treated mathematically by the modified Newton's law, FN= η’G, the exponential constant N was found to Increase with Increasing concentration of gum. The viscosity of the solutions remained fairly constant in the pH range from 1.5 to 10.5.
