At this moment there are no hydraulic piping stand- ards available which cover different pressure classes and piping materials as well as being gener- ally suited for all applications.
A high concentration simply means there is a high percentage of solute particles dissolved in the solvent and the solution is said to be concentrated. And a low concentration means there is not a high percentage of solute particles in the solvent and the solution is said to be diluted. high concentration of something, like a hormone in the blood, means there is a lot of it. A low concentration of something means there is not a lot of it, but a little.
concentration. 1. increase in strength by evaporation. 2. the ratio of the mass or volume of a solute to the mass or volume of the solution or solvent. hydrogen ion concentration. an expression of the degree of acidity or alkalinity (pH) of a solution.See also acid-base balance.. the ratio of the mass or volume of a solute to the mass or volume of the solution or solvent. hydrogen ion concentration. an expression of the degree of acidity or alkalinity (pH) of a solution.
