We are required to describe the relationship between flow, pressure, and resistance using the basic flow equation.

Poiseuille equation:

$\overline{){\mathbf{Q}}{\mathbf{=}}\frac{\mathbf{\u2206}\mathbf{P}\mathbf{\pi}{\mathbf{r}}^{\mathbf{4}}}{\mathbf{8}\mathbf{L}\mathbf{n}}}$

Which of the following equations correctly relates flow, pressure, and resistance?

A) resistance = flow × pressure

B) pressure = flow × resistance

C) flow = pressure × resistance

D) flow = pressure - resistance

E) flow = pressure + resistance
