Sand Blasting - Standards

I need to know the Air Pressure required and Air Delivery ration required for the sand blasting equipment to obtain SA 2.0, SA 2.5 and SA 3 finish. Also Please let me know on which standard codes the SA2.0, 2.5 and 3 comes under. Thanks much in advance.

The effect of a single impact of a flying object over a target is something complex to analyze. Now, imagine to multiply that times several billions. That would be a model of a sand blast operation. The pressure of the gas used to impel the particle or its available volume per second only mean a fraction of the needed information to calculate one of the significant variables, the attained speed at impact. And there are many other variables such as particle mass and shape, angle of impact, hardness of both particle and target, etc.
