The fact that viscosity is measured from laminar flow in a pipe does not mean that it has no significance in other modes of flow. The fact is that the use of laminar flow is just a means to quantify a property of the molecular structure of the liquid and is not dependent on the way that it is measured. Of course the viscosity will be important in many practical applications in engineering like bearings and oil hydraulics but it also has an important role in creating storage and retrieval systems in our empirical science and a pivotal role in computer fluid dynamics.
