| | CONDUCTANCE (HYDRAULIC ) | | Description | The factor relating the resistive pressure difference to the flow of a fluid in the case of laminar flow. It is equal to the slope of the straight line in the flow characteristic. It is the inverse of the flow resistance. | | Symbols | G_V | | Relations |  The characteristic line with the larger slope has the larger value of the conductance. | | Units | [G_V] = m^3/(s·Pa) | | Synonyms | flow factor | | Related to | | | Remarks | In the case of laminar flow through circular pipes, the hydraulic conductance 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. | | German | hydraulischer Leitwert | | |  | | |
