2018-9-25 · the viscosity (Pa*s). Dynamic viscosity, also called apparent viscosity, describes a fluid s resistance of deformation (Pevere & Guibad, 2005). In terms of rheology it is the relation of shear stress over the shear rate (Eq. 4). For Newtonian fluids the dynamic viscosity maintains a constant value meanin g a linear relationship between W and J.

Phosphate Hill is a mine site located in North West Queensland. At the site, mined phosphoric rock is reacted with sulphuric acid to produce phosphoric acid. The phosphoric acid is combined with ammonia in a reactor known as the pre-neutraliser. The reaction forms a very hot and viscous slurry which is later further ammoniated in a cylindrical vessel known as a granulator, to produce solid .
