There are ways to increase the pressure for waterjetting to levels above 20,000 psi. What are the effects of different pressures (below and above 20,000 psi) on cleaning ratios?

As you go up in pressure, the energy density goes up and it rips /cuts the coating from the surface. You can use a faster transverse rate, to get a higher productivity.
Think of a water hose. Clean with the hose, then put your finger over it to block part of the opening; the water moves faster, and you get faster cleaning.
Then put on a nozzle that has a small hole in the center. The velocity goes up and the cleaning is faster.
