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.
Chemical Precipitation. Precipitation is the creation of a solid. When the reaction occurs in a liquid solution, the solid formed is called the 'precipitate'.The chemical that causes the solid to form is called the 'precipitant'.he silver chloride (AgCl) has formed a solid, which is observed as a precipitate. This reaction can be written emphasizing the dissociated ions in a combined solution. This is known as the ionic equation.
