Venturi effect

And then I finish the lap, and indeed, like, I feel my face going sideways through some corners.

So I'm like, "What the hell?" And then, then I'm like, "What did you do?" He's like, "Oh, yeah, I done here some diffusers and some Venturi tunnels-

[laughs]

... and a splitter, but I'm still a, a student, and, uh, don't take my word for it because I designed it, but I didn't have the wind tunnel because my other classmate had it booked, and we need to still verify that and this and that, and, uh, by the way, I'm still looking for graduation project, and, uh, can someone offer me an internship?"

Uh-huh.

It's got a different Venturi, uh, more styled towards a bullet Venturi.

Uh, the Venturi, uh, is a much stronger signal with the, uh, drops the pressure.

Uh, so-

Uh-huh

You know, and then all the dimensions and everything is recorded, so we have objective evidence on all of our product of what it measured, where the metal came from.

So there's traceability throughout the whole system.

So if you give us your serial number, within about 15 minutes, we can pull up the whole data package of what that measured, how it flowed on the flow bench, uh, who inspected it, who made all the parts, for every component in there, from a cotter pin all the way up to your, your Venturi, your main housings, your float, your diaphragms.

Instantly.

Let's explain exactly why using the laws of fluid dynamics, specifically the Venturi effect or Bernoulli's principle.

Think about taking a massive wide flow of moving air, which is what a tornado is, and forcing it to squeeze through a narrow concrete channel, which is the tight V-shaped space underneath the highway overpass where the embankment meets the bridge deck.

It's exactly like putting your thumb over the end of a garden hose.

And bucket two is the semi-dry type.

But when officers think semi-dry, they picture a very specific classic arrangement using a Venturi nozzle.

Okay.

Because the Kashiwa unit on their deck had traditional external fittings and didn't look like that classic Venturi sketch, their brains simply defaulted to bucket one, the wet type.

Even though it wasn't.

Right.

Oh, a ton of splashing and moisture carryover.

Right, yeah.

complicated.

It's more complicated because this thing has a variable Venturi carburetor.

Yeah.

There's some controller on it that it's proprietary, and Toyota won't tell me about it unless I take it in.

Is that air path still open? Think of it as leaving a controlled leak open so suction cannot become strong enough to pull the trip.

During a normal fill, the Venturi continually draws air through the exposed sensing port, limiting vacuum in the diaphragm chamber.

When liquid or foam blocks the sensing port, vacuum rises in a diaphragm chamber.

The diaphragm moves a release mechanism, the lever loses its supporting latch, and a spring closes the main valve.

The system keeps asking one physical question.

Is that air path still open? Think of it as closing one tiny window and changing pressure throughout the handle.

When liquid covers the sensing port, air can no longer bleed freely into the vacuum circuit and the Venturi continues pulling on the closed passage.

When liquid or foam blocks the sensing port, vacuum rises in a diaphragm chamber.

It was just sucking it like a straw.

Yeah, it was actually acting like a fucking Venturi.

You know what I mean? The BGV was open so far, it was just...

What can I take out?

Well, they did some loop-de-loop on it.

But the problem is, you've got to imagine, okay, you've got oil coming in.

got oil going out, it's acting like a Venturi.

Yeah.

The real achievement is Sutler, producing enormous downward force efficiently, distributing it between four temperature-sensitive tires and keeping it predictable while the vehicle moves through a constantly changing three-dimensional flow field.

Venturi tunnels.

A narrowing passage accelerates flow before a controlled expansion recovers pressure without allowing the boundary layer to separate.

You know, NASCAR fans appreciate a good pit strategy.
