	Poiseuille's law - Wikipedia, the free encyclopedia
		The law can be derived from the Darcy-Weisbach equation, developed in the field of hydraulics and which is otherwise valid for all types of flow, and also expressed in the form:
		The theoretical derivation of slightly different Poiseuille's original form of the law was made independently by Wiedman in 1856 and Neumann and E. Hagenbach in 1858 (1859, 1860).
		The Poiseuilles' law was later in 1891 extended to turbulent flow by L. Wilberforce, based on Hagenbach's work.

		In this form the law approximates the friction factor, the energy (head) loss factor, friction loss factor or Darcy (friction) factor Λ in the laminar flow at very low velocities in cylindrical tube.
		The law is also very important specially in hemorheology and hemodynamics, both fields of physiology.
		Poiseuille's law corresponds to the Ohm's law for electrical circuits, where pressure drop Δp

	Enhanced tolerance of high-p plants to environmental stresses is related to primary root diameter and potential root ...
		In this study we aim to examine whether increased root thickness and/ or changes in xylem diameter and density of primary roots can explain the beneficial effects of high P levels on tolerance of plants to environmental stresses.
		Key measurements were made of the biomass, water uptake, leaf area and leaf expansion rate, thickness of basal primary roots, size and density of xylem vessels (as noted from the cross section of the thickest nodal root for white clover and wheat, or the tap root for cotton).
		The potential hydraulic conductance of basal primary roots was estimated from the mean diameter and mean number of xylem vessels in the primary roots (Hagen-Poiseuilles law) (7).
