You'll need to pull the water through the j-tube, but if the Re number in the water is the same as it would be with the air then you're all good to go. Since water is so much denser than air the flow rate won't need to be nearly as fast as it would with air to get a good simulation. This is why water tunnels are so useful when a wind tunnel isn't in the cards. I wouldn't discount all your observations grippy, I bet they were pretty close...you'd be surprised.

 

Hey Grippy, I like the way your always thinking.....
How about hooking up a shop vac to the blower flange side and turn it on? Then take a 12" piece of string and let it float inside the throttle body side of the flange down the J-tube. This will help you visualize what the airflow is doing under more normal circumstances. Of course it will only tell you what's happening on the ttb side of the J-tube curve, but you'll be able to see how the highest pressure of air will gather around the inside of the turn.

Just my 2¢

quit goofing off and start installing parts.

 

Can I have some of your free time.......

 

what the hell is a graden hose? (thread title)

You know, when I was in the Navy and goofing off (22hours a day) on our west pac, I was an ordie, but we played around with shooting hydraulics through manifolds and stuff, and I was always blown away at what appeared to be an inefficient airflow result via hydraulic fluid. Not the same scale your talking about but, same theory.

 

Did it suck a golf ball through the hose ?

 

Can you?

 

No, but I heard your 6.0 can

 

Well I hooked up my leaf blower/vacuum to the discharge side of the J-Tube and flow tested some 12" lengths of string to see what would happen. I tested it in 3 slightly different orientations, with the last being the best representation I think. Anyhow, much different results, I'll let the video speak for itself.

Note: I apologize for the language in the song I had playing in the garage while I was recording this. I didn't realize it until after I played back the video.

How about smoke. Get a cigarette and just hold it in the inlet. Got any smoke bombs left over from the 4th? Interesting test though.
I kept waiting for a golf ball!

And my 6.0 couldn't suck a golf ball through **** right now .
