Any process flow through piping and control valves is almost always considered as turbulent. The reason being the process has to go through so many twists and turns, expansion, reduction in piping, and elbows, valves, etc.

Unless your flow is in a straight pipe from point A to point B without connections, any flows would be a turbulent flow.

Scientifically speaking, you can use the Reynolds number to calculate whether a flow is laminar or turbulent.

Reynolds number (Re) = VL / v

Where:
V = 
velocity of the object relative to the fluid
L = Length of the sytem in linear dimension
v = Kinematic viscosity
