Growths on the surface of the eye can be unsightly and frightening. Most growths on the eye, which often occur as people age, pose no threat to health or vision and aren&rsquo;t cancers.
The unit of measure for static pressure is often inches of water (in. water). one inch of water is the suction needed to draw water up a straw one inch. pound per square inch static pressure (1 psi) is equal to 27.7 in. water static pressure. static pressure is given as Pascals (Pa).
This is because the static pressure is increased from the additional weight of water above. This increase in pressure is linearly related to the depth, wâ¦hich at sea level adds about 4.5 psi for every 10 feet of depth.
