Topic: Squirting water

So whadya know about fluid dynamics?

If I squirt water through a plastic tube that has spiraling inside it, like the rifling in a gun barrel, will the water squirt straighter or further than if I just use a plain tube?

Re: Squirting water

I'm no expert, but I would surmise that whatever rifling action is imparted to the water stream it would:
- Be lost very shortly after exiting the tube and the water would continue on straight in the last direction it was moving...
     and
- If any spinning action were to remain in the stream (unlikely), then that would just cause it to disperse more due to centrifugal force once unconstrained.

Re: Squirting water

I am going to say the water will exit in an expanding spiral fan effect. Like a blooming flower and have little range. The rifling will make the water spin. Since water has mass that spin will pull that mas outwards. In the tube it is confined but once it exits the mass will be pulled outward causing a blooming effect.

Re: Squirting water

I saw a tv show about the water show at Bellagio in Vegas.  To keep the water in blobs, they go to great effort to get it all travelling in a straight line. 

I expect the others are correct about how it would exit a rifled tube.

Re: Squirting water

When I pee, it comes out spiralling. I can knock a gnat off a pin head at thirty yards.

(Now everyone will go pee to see if theirs does too!)

Re: Squirting water

If there was just some way to prototype a rifled water tube... Oh! I know!

Re: Squirting water

Grab an old rifle barrel and clamp a water hose to it.  Let us know what happens

Also, you may want to see a doctor. smile

If you build it they will come. Then they will make fun of it, tell you it's not worth doing and go home and try to copy you.

Re: Squirting water

Well, I emailed the people that engineered the dancing waters at the Bellagio and many other places and here's the reply I just got.

Hello Kent,

The answer I got from our staff is that it will fly off to the sides
because of angular momentum.

Should I challenge them about my pee?

I wouldn't. They may start commenting about the smaller diameter of your "pipe".
