Thermodynamics and kinetics of silica scaling
One further required definition is the silica saturation index (SSI). This is defined as the ratio of the silica concentration in the brine divided by the equilibrium amorphous silica solubility at the conditions prevailing. If SSI >1.0 then silica scaling is possible, if SSI <1.0, then generally, silica scaling will not occur. 3.

— A cantilevered pipe conveying fluid is a non-conservative system and loses its stability for a sufficiently high flow velocity. When a fluid-conveying pipe is involved as a structural element in a mechanical system (e.g., in oil and gas industry), it is often preferred to maximize the critical flow velocity in the pipe.
