The pressure of the water exerted in a soil
WebbPore water pressure here becomes unit weight of water multiplied by soil deposit height. u = γ w (H 1 +H 2) Hence effective stress can be calculated as this. σ' = σ − u. σ' = γ sat (H … WebbIn fluid mechanics, pressure head is the height of a liquid column that corresponds to a particular pressure exerted by the liquid column on the base of its container. It may also be called static pressure head or simply static head (but not static head pressure).. Mathematically this is expressed as: = = where is pressure head (which is actually a …
