<prompt> Answer this question truthfullyWhat does Poiseuilles law state?  <response>: <reason> Electricity was originally understood to be a kind of fluid. This hydraulic analogy is still conceptually useful.Poiseuilles law corresponds to Ohms law for electrical circuits V IR, where the pressure drop Δ P is analogous to the voltage V and voluminal flow rate Φ is analogous to the current I. Then the resistanceR frac 8 eta Delta xpi r4This concept is useful because the effective resistance in a tube is inversely proportional to the fourth power of the radius. This means that halfing the size of the tube increases the resistance to fluid movement by 16 times.Both Ohms law and Poiseuilles law illustrate transport phenomena.
