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.
Boiling-point elevation describes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water.
