A conservative estimate from Gartner pegs the hourly cost of downtime for computer networks at $42,000, so a company that suffers from worse than average downtime of 175 hours a year can lose more than $7 million per year. conservative estimate from Gartner pegs the hourly cost of downtime for computer networks at $42,000, so a company that suffers from worse than average downtime of 175 hours a year can lose more than $7 million per year.
Fractional Precipitation. a method of separating a mixture of substances by means of their gradual precipitation from a solution.he methods of fractional precipitation, which are generally used for separation of mixtures of substances that are close in terms of chemical properties and solubility, are extremely labor-intensive. Kolthoff, I. M., and E. B. Sandell.
Precipitation in chemistry refers to the creation of a solid within a solution or within another solid during the process of diffusion. During this process, the solid formed is known as the precipitate. What causes the solid to form is known as the precipitant, and the supernate or supernatant is the area above the precipitate.
