Laminar versus Turbulent Flow
Smooth running water flows faster than rough, turbulent water!
Let me explain.
Take your ordinary garden hosepipe attached to the tap, turn on the tap and watch the water flow freely. Slowly increase the flow from the tap and correspondingly the flow from the end of the hosepipe increases until suddenly the water no longer flows freely but has become turbulent. At this point you will also observe that LESS water now flows from the hosepipe than before! Why?
