In case of stationary homogenous isothermal fluid flow the pressure gradient model can be correlated to fluid velocity as:

|---|
|
G_p = G_{p0} + b \, q^n |
The constant term is related to pressure gradient in static fluid column:
| LaTeX Math Block |
|---|
|
G_{p0} = \rho \, g \, \cos \theta |

In smaller range of flowrate variations this can be simplified to:
