At a pressure drop per unit length of 0.28 mmHg cm−1, i.e., ΔP/L, the measured flow rate of the fluid through the capillary viscometer was found to be 0.0125 cm3 s−1. When the value of ΔP/L was increased to 0.79 mmHg cm−1, the flow rate of the fluid was found to be .047 cm3 s−1. Under these conditions, is the fluid Newtonian or non-Newtonian?
