hydrostatic pressure

[‚hī·drə′stad·ik ′presh·ər]
(fluid mechanics)
The pressure at a point in a fluid at rest due to the weight of the fluid above it. Also known as gravitational pressure.
The negative of the stress normal to a surface in a fluid.

hydrostatic pressure

The pressure equivalent to that exerted on a surface by a column of water of a given height.

At the impact of hydrostatic pressure the locking fluid under a pressure, equal to an ambient pressure, is supplied from a source to the primary locking chamber 8.
Using Equations (14), (15), and (16), we can get the curves between friction angle [phi] and hydrostatic pressure with different salt contents 0.0,0.5,1.5, and 2.5%, shown in Figure 4.
It is not excluded that longer HHP treatment might impair stability of the maternal mRNA as it has been observed in the pig oocytes after one-hour exposure to 20 MPa of hydrostatic pressure [24].
Figure 8 shows the predicted relative bubble radius as a function of the dimensionless treatment time, [t.sub.r]=t/[t.sub.p] at various bubble volume fractions of 0.33%, 0.67%, and 1.33% at an ultrasonic amplitude of 10 [micro]m and a hydrostatic pressure of 1 MPa.

The increase in hydrostatic pressure causes an additional noticeable decrease in the permeability.
To address the aforementioned issues, we determined which pressure level could cause RGC-5 cells death, whether laminin expression is changed under hydrostatic pressure in vitro , and whether laminin can contribute to the survival of RGC-5 cells through [sz]1 integrin-FAK-AKT pathways.
Here, the court did not look at the point in time when the valve failed, it looked at the point in time that the failed valve contributed to the loss, and the failed valve and the hydrostatic pressure contributed concurrently to the loss.
Available in two styles, the sensors provide liquid level measurement by continually sensing hydrostatic pressure produced by the height of liquid above the sensor and providing a 4-20 mA output signal compatible with PLCs, panel meters, data loggers, and other electronic equipment.
