WebCapillary entry pressure (P ce capillary entry pressure) ... Also, in a low-moisture vadose zone setting above the water table, even non-wetting DNAPL can be subject to capillary spreading, as DNAPL often acts as a wetting fluid relative to air. Below the water table, most but not all DNAPLs behave as non-wetting fluids.
