porous media flow

hello

i'm trying to use hydraulic head(=((P/(rho*g))+(z)) as the variable in place of pressure to solve discritized form of the momentum and continuity equations. The SIMPLER ALGORITHM is what I'm trying to use to obtain pressure and velocity field. what are corrections I've to make in discretized equations? flow is incompressible, inviscid and steady state. thank you in advance.
