WebTypical flow curves are shown in F i g u r e 2. Newton-ian flow (A curve) is the simplest type, displaying a s h e a r -independent viscosity while the material is sheared. Water and some low-molecular-weight mineral oils are typical examples of Newtonian fluids. Pseudo-Application Note 12 / JULY 1998 The rheology of pharmaceutical and cosmetic ... WebNov 1, 2011 · Flow curve. After a conditioning step of 2 min, the shear rate was increased from 0.1 s − 1 to 100 s − 1. The flow curve is then obtained by plotting the recorded shear stress (Pa) as a function of the applied shear rate (1/s). Viscosity and yield stress values were obtained by fitting the Casson equation to the data.
