Class
    Foam::PrghPressureFvPatchScalarField
 
Description
    This boundary condition provides the p_rgh equivalent of a pressure
    boundary condition calculated as:
 
        \f[
            p_rgh = p - \rho g (h - hRef)
        \f]
 
    where
    \vartable
        p_rgh   | Pseudo hydrostatic pressure [Pa]
        p       | Static pressure [Pa]
        h       | Height in the opposite direction to gravity
        hRef    | Reference height in the opposite direction to gravity
        \rho    | density
        g       | acceleration due to gravity [m/s^2]
    \endtable
