we have at each cell descretised equation in this form,
;
For continuity we have
![\sum\limits_{faces} \left[ {\frac{1}{{a_p }}H} \right]_{face} = \sum\limits_{faces} \left[ {\frac{1}{{a_p }}\frac{{\nabla p}}{V}} \right]_{face}](/W/images/math/8/7/1/8716a0f2e3b6892c158df26a9c5b8c67.png)
where
This interpolation of variables H and 
based on coefficients 
for pressure velocity coupling is called Rhie-Chow interpolation.
