Could some expert please explain what “chénliú” and “duānliú” mean? Thank you

In a “laminar” flow, the velocity is relatively low; as the fluid flows through the pipe, the protons move along the axial direction of the pipe, with no radial movement. “In “turbulent” flow, the velocity is high, and protons move radially as well as along the axial direction of the pipe. Most flow meters require the fluid to be in a turbulent state, with a Reynolds number greater than 10,000.
You’re really good; I stared at the title for a long time without understanding what the original poster was talking about, thinking that the person had posted in the wrong forum! Is this a dialect? !
Distinguish by calculating based on the Reynolds number!
It should have been heard, but there was a mishearing; P
