Question

Modern AWJ machines generate water cutting pressures of 800 psi and cutting jet velocities approaching 200 mph. (True or False)

Answer 1

The statement is FALSE. Modern AWJ machines generate much higher water cutting pressures than 800 psi and cutting jet velocities than 200 mph.

Step-by-step explanation:

The statement is FALSE. Modern AWJ (Abrasive Water Jet) machines do generate high water cutting pressures, typically ranging from 30,000 to 55,000 psi, depending on the specific machine. They also produce cutting jet velocities that can exceed 600 mph.

To put it in perspective, the given values of 800 psi and 200 mph are much lower compared to actual capabilities of modern AWJ machines.

For example, a pressure of 800 psi would be equivalent to about 55 times less than the lower range of cutting pressures typically generated by these machines.
