pressure in laminar flow

I am running a CFD simulation using the laminar flow module. The module uses Navier Stokes equation in ahich the fluid velocity is the dynamical variable. The equations it is solving are clearly stated in the "equations" section of the module. However it also calculates pressure but I cannot se in the documentation how it is calculating pressure from velocity. Does anyone know what assumptions are being made when COMSOL calculates pressure in the laminar flow module?
