Fluid mechanics and English help

[mech-eng]

My native language is not English. I follow a series of vids about Ansys Fluent. I am not stuck in 2.59 about the part "so VR" and "so we are in a velvet in laminar regime." Would you please explain those parts. This is about my project and it is about calculation of pressure losses in pipes in Fluent.



Thank you.

Would you look this part as well. What does "axymetric assumption built into mathematical model" in 0.17. I especially confused the part "built into".



Thank you.

He is saying, "so we are in the laminar regime."

Is velvet there something like exactly? It think it is very strange saying as VR. And your quote seems for the other one.

Thank you.

What does "that's going to be like a swell" in 3.07

I think the word he said is swirl, but I'm not sure. Neither work makes sense to me.
