For this case, in general
Re less than 2300 - laminar
Re more than 4000 - turbulent
Haha. I don't think the flow is laminar la. Coz liquid must always been turbulent. I think what she wanted to mention about the equation is Re = VD/v, since when we check for the dimension for VD/μ, it has dimensions since the Reynolds number is supposed to be dimensionless. I tried calculate for Re = VD/v and I found that the number is large, that is turbulent. And that must be logical. I think when I use back Re = ρVD/μ, can get the same answer like turbulent.
I don't know what will happen next after Dr. marked our test papers. I'm sure there will be arguments from us. Just watch out. Haha.
