Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.

Question

Would the volumetric flow rate in a pipe,
assuming laminar flow, be more or less if
the fluid were more viscous, but the
pressure gradient, dP/dz was the same in
both cases? Use formula for the volumetric
flow rate to answer, but explain why the
result makes sense using the meaning of
viscosity.
