Why do waterproof clothing fabrics have a " hydrostatic head "?
2.
Forced circulation occurs when hydrostatic head prevents boiling at the heating surface.
3.
Rain resistance is measured and expressed as hydrostatic head in millimetres ( mm ).
4.
Power is recovered from both the hydrostatic head and from the kinetic energy of the flowing water.
5.
The depth to water ( hydrostatic head ) averages 14 feet below the surface, closely correlated with topography.
6.
This creates a hydrostatic head in the downcomer, meaning that the pressure inside the top of the downcomer is lower than the atmospheric pressure.
7.
However, the hydrostatic head supplied by this mechanism could not feed the numerous channels at elevations greater than the base of the southern polar cap.
8.
Fabric with a hydrostatic head rating of 1000 mm or less is best regarded as shower resistant, with 1500 mm being usually suitable for summer camping.
9.
At 1 : 13 p . m ., the three pressure relief valves were forcibly opened as the hydrostatic head pressure of the raffinate built to over above atmospheric pressure.
10.
:: : : : When drilling very deep wells ( typically looking for petroleum ), most of the pressure at depth is kept at equilibrium by the hydrostatic head.
