The hydraulic resistance (or simply flow resistance) is the inverse of the hydraulic conductance: R_V = 1/G_V.

R_V

The characteristic line with the larger slope has the smaller value of the resistance.

[R_V] = Pa·s/m^3

hydraulic conductance, laminar flow laws, conductive transport, resistive transport, Ohm's law

In the case of laminar flow through circular pipes, the hydraulic resistance is calculated according to the law of Hagen and Poiseuille:

delta_pR: resistive pressure difference, r: radius or pipe, eta: viscosity of fluid, l: length of pipe.
