How to calculate nozzle orifice diameter for a given fluid flow rate to have a laminar output stream rather drips (orifice too large/ flow rate too small) or turbulent flow (orifice to small / flow rate too large)?

Think how a faucet acts as you increase the flow rate, initially it drips, then you get a laminar flow and lastly it becomes turbulent. I have a small range of flow rates centered around 10ml/min. I need to design a nozzle whose output is a nice laminar flow but I'm at a loss to know how to calculate it.
