Hydrostatic head:
- a way of describing the pressure applied to a material in terms of the height of an equivalent column of water. Because the pressure exerted is determined solely by the height of the column, it is possible to use this figure to quantify how waterproof a fabric is. For example, a fabric which can withstand a hydrostatic head of one metre will resist the passage of water until the pressure of the water exceeds this value.
