Etukudo. Equivalent fluid pressure (EFP) is a simplification of the lateral loading that the soil exerts on an earth-retaining wall. Moreover, the equivalent fluid refers to a hypothetical fluid, having a unit weight that produces pressure against a lateral support of which its value is presumably equal to that the actual soil produces.
