I have this experimental tank (38 x 9 x 9 cm) that has a circular inlet of 1.2 cm diameter. In my experiments, I have the flow coming in at the rate of 60 mL/minute. Now the problem is - when I have to simulate this in CFD, I need the velocity of flow coming in.
So, from the equation Q = V.A, I can get the inlet velocity, but I am simulating this in 2D (38 x 9 cm), where the inlet is represented by a line 1.2 cm in length. What will be the inlet velocity for this case? Will it be the same as I get from the above equation for 3D simulation?"
