  2. Hydrostatic head - Wikipedia

    en.wikipedia.org/wiki/Hydrostatic_head

    Hydrostatic head is also used as a measure of the waterproofing of a fabric, commonly in clothing and equipment used for outdoor recreation.It is measured as a length (typically millimetres), representing the maximum height of a vertical column of water that could be placed on top of the fabric before water started seeping through the weave.

  3. Hydraulic head - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_head

    On Earth, additional height of fresh water adds a static pressure of about 9.8 kPa per meter (0.098 bar/m) or 0.433 psi per foot of water column height. The static head of a pump is the maximum height (pressure) it can deliver. The capability of the pump at a certain RPM can be read from its Q-H curve (flow vs. height).

  4. Pressure head - Wikipedia

    en.wikipedia.org/wiki/Pressure_head

    So, for any particular measurement of pressure head, the height of a column of water will be about [133/9.8 = 13.6] 13.6 times taller than a column of mercury would be. So if a water column meter reads "13.6 cm H 2 O ", then an equivalent measurement is "1.00 cm Hg".

  5. Hydrostatics - Wikipedia

    en.wikipedia.org/wiki/Hydrostatics

    p is the hydrostatic pressure (Pa), ρ is the fluid density (kg/m 3), g is gravitational acceleration (m/s 2), z is the height (parallel to the direction of gravity) of the test area (m), 0 is the height of the zero reference point of the pressure (m) p_0 is the hydrostatic pressure field (Pa) along x and y at the zero reference point

  6. Bernoulli's principle - Wikipedia

    en.wikipedia.org/wiki/Bernoulli's_principle

    The hydrostatic pressure p is defined as =, with p 0 some reference pressure, or when rearranged as head: =. The term ⁠ p / ρg ⁠ is also called the pressure head, expressed as a length measurement. It represents the internal energy of the fluid due to the pressure exerted on the container.

  7. Well kill - Wikipedia

    en.wikipedia.org/wiki/Well_kill

    The pressure of the reservoir fluids at the bottom of the hole is 38 MPa.We have a kill fluid with a weight density of 16 kN.m −3.What will need to be the height of the hydrostatic head in order to kill the well?

  8. Hydraulic accumulator - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_accumulator

    Water was pumped to a tank at the top of these towers by steam pumps. When dock machinery required hydraulic power, the hydrostatic head of the water's height above ground provided the necessary pressure. These simple accumulators were extremely tall. For instance, Grimsby Dock Tower, built in 1852, is 309 feet (94 m) tall. Because of their ...
