Engineering LibreTexts Gravity Pressure Loss

Gravity was discussed in Chapter 4 and is
    \left.\dfrac{dP}{dx} \right|_{g} = g\,\rho_m\, \sin\theta
     \label{phase:eq:Pgravity}  \tag{38}
The density change during the flow can be represented as a function of density. The density in equation (38) is the density without the "movement'' (the "static'' density).
