The pressure at E is given by . If a graph is drawn of shear stress versus shear rate, the slope of the graph will be a straight line.
Water is an example of a Newtonian fluid.
Its viscosity does not change as increased pressure differences cause increase flow. If a graph is drawn of shear stress versus shear rate, the slope of the graph will not be a straight line. Many types of paint are non-Newtonian. Capacitors are used to store charge and electrical energy. Due to transport of ions across cell membrane, charge builds up on each side of the membrane.
