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).
Static Pressure or simply 'pressure' is the force per unit area applied in the direction perpendicular to a surface. It has to be noted that this definition is only applicable to static fluids (dynamic pressure for fluid in motion).The idea of pressure is as 'stress' in solid mechanics.
