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 concentration gradient is the graduated difference in concentration of a solute within a solution (in osmosis and diffusion). The greater the difference in concentration of â¦particles, the steeper the gradient.
