Turbo Funnel #2

Building a Better Turbo Funnel (revised)
========================

This project is a remake of [Turbo Funnel thing:4925561](https://www.thingiverse.com/thing:4925561).

The original project says "We all know very well that water acquires special properties when it swirls and is able to flow at a higher speed through narrow obstacles." - but do we? Does this swirl design make a better funnel?

If water is rotating in our funnel then would not the centrifugal force lower the pressure in the centre reducing the flow?
Whilst water flows somewhat faster through a constriction owing to pressure effects, the actual volume of water is reduced by the area of the constriction. If we make a funnel with a smaller spout it would run slower.

I ask would the swirl pattern on the bowl of the Turbo Funnel have sufficient influence on the flow of water during its brief time in the funnel? I had my doubts but it is an intriguing idea so I decided to put it to the test.
