According to the Poiseuille equation, which of the following does not directly affect flow rate?

Question

Quizplus · Accepted Answer

The Poiseuille equation describes the flow rate of a fluid through a cylindrical tube, which is directly affected by the viscosity of the fluid, the radius of the tube, and the pressure difference across the tube. Temperature can affect flow rate indirectly by changing the viscosity, but it is not a direct factor in the equation itself.
