I'm trying to get my head around the concept of electrochemical machining and if it would be possible to measure the pressure drop across a pipe as the process is ongoing at a given flow rate to ultimately calculate the amount the pipe has been eroded.

Would the Hagen-Poiseuille equation apply in such a setup?

  • $\begingroup$ If you know the reaction, the amount of material electrochemically removed can be determined by measuring the electrical current during the reaction. This should be a more robust method than using pressure drop. $\endgroup$ Oct 26, 2022 at 18:12
