The proportionality factor in the Darcy's equation is known as:
डार्सी के समीकरण (Darcy's equation) में समानुपाती कारक (proportionality factor) को क्या कहा जाता है?

Darcy's law for flow through porous media is stated as:

\[q = -K \frac{dh}{dl}\]

where:
\(q\) is the specific discharge / flux density
\(\frac{dh}{dl}\) is the hydraulic gradient \(K\) is the constant of proportionality, which is universally known as the Hydraulic Conductivity (or hydraulic permeability coefficient).

Therefore, the proportionality factor in Darcy's law is the hydraulic conductivity.

डार्सी का नियम (Darcy's Law):

\[q = -K \frac{dh}{dl}\]

जहां \(q\) प्रवाह दर (flux) है और \(\frac{dh}{dl}\) हाइड्रोलिक प्रवणता है। इसमें समानुपाती स्थिरांक \(K\) को हाइड्रोलिक चालकता (Hydraulic conductivity) कहा जाता है।
