(b) 10 – 150 µm

(c) 200 – 500 µm

(d) 500 – 1000 µm

I have been asked this question in an interview.

My question comes from Abrasive Water Jet Machining in division Mechanical Processes of Advanced Machining

Answer 1

Right answer is (b) 10 – 150 µm

To elaborate: Grain size of the abrasive particles range between 10 – 150 µm in Abrasive water jet machining.
