Viscosity of a fluid is that property which determines the amount of its resistance to a shearing force
Viscosity is due primarily to interaction between fluid molecules
Viscosity of liquids decreases with increase in temperature
Viscosity of liquids is appreciably affected by change in pressure

Velocity, depth, pressure, etc. change from point to point in the fluid flow.
The fluid particles move in plane or parallel planes and the streamline patterns are identical in each plane
