The ground around your basement walls contains a lot more than dirt. Water filters its way through the soil, keeping our plants and gardens healthy, but where does it go when it hits your foundation?

When this occurs, hydrostatic pressure at the bottom of the form drops off to less than full fluid pressure. This "modified hydrostatic pressure" is influenced by the weight of the fresh concrete ...

and convection by pressure gradients composed of hydrostatic and oncotic components. The balance between hydrostatic and oncotic pressures in tissues and vessels determines the net flow of fluid.

Consider the steady, flow of a constant density fluid in a converging duct ... When streamlines are parallel the pressure is constant across them, except for hydrostatic head differences (if the ...
