The zero shear viscosity is the value of the apparent viscosity (quotient between shear stress and shear rate) of a liquid in the limit of zero shear rate (i.e., when the fluid it is at rest). Therefore it is not the result of a direct measure but a calculus or interpolation from experimental results at the lower shear rates values. The most important thing is its physical meaning. It represents the ability of the material to avoid sedimentation when storage. A high zero shear viscosity is interpreted as a the material will show homogeneous during long storage.
keep temperature in control
The viscosity of a substance will change with both temperature and pressure. For liquids the changes induced by a change in temperature are usually more readily observed than the changes from pressure because liquids are only slightly compressible with pressure. In gasses, the changes in viscosity with pressure are much more easily demonstrated because gases are, almost by definition, quite compressible so that the density can be easily changed by either changes in pressure or changes in temperature.
It is pretty low, close to zero.
Zero (0) gauge pressure equals 14.696 PSI on the absolute scale. A lot of people will round up to 14.7 PSI for simplicity. 14.696 PSI is the pressure that is developed at sea level due to the weight of our atmosphere. The absolute pressure scale is based on zero being a perfect vacuum. Gauge pressure takes into account the atmospheric pressure at sea level (14.696 PSI). A simple conversion formula is PSIG+14.696=PSIA.
The definition of pump shut-in pressure is the amount of pressure that is generated by the pump when it is at zero flow, or not flowing. This can also be called "dead head pressure."
To answer my own question :), if I interpret the differentials correctly, viscosity does have its maximum when there are no shearing forces, regardless of whether the fluid is newtonian or not. So, in short, yes.
Shear rate and viscosity are related to each other. According to shear rate and viscosity we can classifying the materials especially paints. Fluids are divided into two types like 1.NEWNONION FLUIDS and 2.NON NWETONINON FLUIDS based on shear rate and viscosity. In fluids if there no change in viscosity with respective shear rate, such type fluids are known as nwetonion fluids. Viscosity changes with respective shear rate such type of fluids are known as non nwetonion fluids.
Viscosity is constant to the flow of the fluid.
Viscosity is the resistance offered against shear force by a fluid.
Ideal liquid has zero viscosity.
Pseudo plasticity discusses to the decrease of viscosity when shear forces are applied. The tougher the shear stress the pseudo plastic material is subjected to, the tougher the shear thinning effect and the tougher the reduction in viscosity.

Pressure and temperature are the two factors that affect flow and viscosity. Viscosity refers to the resistance of a liquid to the shear forces.
A liquid resistance to shear force or flow.
shear thickening viscosity and density increase during flow
The viscosity of oil is the rate that it flows, and its resistance to shear forces.
