Dear Jack,
I would like to get answers to the following questions. We are busy rebuilding an old shotpeening machine with which one of our senior lecturers want to do research.
The questions that I've got has to do with repeatability and accuracy.
1. How constant is the shot flowrate with a pressure peening system?
Is there a certain tolerance within which the flowrate must be?
How can one measure the shot flowrate, while the system is in operation?

2. What will be the variation in intensity with the variation in distance between the object and nozzle?

3. What will happen to the shot intensity if there is small pieces of rust inbetween the shot. The shot will be screened.

4. If accurate shotpeening must be carried out, what will be the maximum allowable variation in the variables, pressure, shotsize, flowrate and distance between nozzle and object.
I am looking forward to hearing from you.
Regards
