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.
A solution is defined as having a solvent along with particles. The solvent that is present in a solution is generally always liquid, but can be made of gas. The particles that are in the solution make up the various chemical differences of the solution. Solute concentration is what dictates the amount of particles that are present in a solution. The concentration of the particles can change depending on the situation and can be affected by different factors, including temperature. Concentration can change when more particles are dissolved within the solution.
