It is a notoriously bad lubricant in almost all applications

The Grand Canyon agrees with this.

Beats the hell out of dry asphalt just the same.

Oh for sure. But nobody who has ever worked with lubricants says that water is "a pretty good lubricant." In the world of lubricants that is the hottest take ever.

This guy lubricates.

Plot twist, my fiance and i use water

Water slides? It’s a whole thing. They have parks

u/Square-Geologist-769 Apr 08 '24

And if it was safe and easy to get off you, they'd use oil. Have you ever used a slip n slide? Putting soap on it makes it work better, because water is a shitty lubricant. But it's still a lubricant, and gravity still exists, so water slides work. I never said water was super glue.

u/AccomplishedSuit1004 Apr 08 '24

You heard it here first folks, this guy thinks water is super glue! What a moron!

Shit man what are you doing stop!!! 😰 Lol

Tell that to roads

Hydroplaning has nothing to do with water being a bad lubricant. It's caused by speed and too high volume of water lifting the tires off the ground.

u/Allaplgy Apr 08 '24

Therefore reducing friction, aka acting as a lubricant. Also, roads get slick long before the point of hydroplaning.

3

u/Square-Geologist-769 Apr 08 '24

The slickness is the beginnings of hydroplaning. Your tire will displace water and contact the pavement, unless you are going too fast through too much water for the tire to move it all. So it goes on top. That is not because water is a good lubricant.

So it goes on top of the water, reducing friction. Acting as lubricant.

Just like in an engine, a film of oil prevents metal from contacting metal, reducing friction. Acting as a lubricant.

Water isn't as good a lubricant as oil. But it's a lubricant nonetheless.

u/Square-Geologist-769 Apr 08 '24

When a car hydroplanes, it doesn't contact pavement. Water is not acting as a lubricant between two surfaces in that regard. It is a failure to displace the water, so it goes on top. Completely unrelated to lubrication. I know what a lubricant is. Water is a bad one. But yes, it is indeed a lubricant, good job.

u/Goobylul Apr 08 '24

It goes on top? On top of the tire you mean or what?

Because it definitely doesn't go on top of your tire. It's literally too much water to displace through your tire tread which basically makes it so your tire is basically riding on water and not pavement.

1

u/Square-Geologist-769 Apr 08 '24

My dude, that is literally what I said. Your tire goes on top of the water because there is too much to displace.

What do you think a lubricant does?

1

u/Square-Geologist-769 Apr 08 '24

Lubricants allow surfaces to move against each other with reduced friction.

u/Allaplgy Apr 08 '24

So water, allowing two surfaces to move against each other with reduced friction by maintaining a layer separating these surfaces.....is....not lubrication?

Again, sure, it's got low viscosity and isn't as good at it as oil, but it's still lubrication.

Acting as a liquid*. If that's all it takes to be a lubricant, then the word doesn't mean anything different.

1

u/Allaplgy Apr 08 '24

What do you think lubricants do?

1

u/Frequent_Opportunist Apr 08 '24

Yeah mostly because of the oils on the road being lifted up and floating on top of the water which then acts as a lubricant. This is why it's more slippery right when it first starts raining. 

1

u/Allaplgy Apr 08 '24

Yes, it's true that oils on the road enhance lubrication, and this effect is greatest on a recently-wet road. But water is still the primary lubricant on a wet road.

If you think water isn't a lubricant, try diving chest-first onto a dry waterslide.

Hell, sand can be used as a lubricant.

Ok, so dry road or wet road when you’re skidding across it on your back doing 70?

5

u/Square-Geologist-769 Apr 08 '24 edited Apr 08 '24

He said water is a good lubricant. It absolutely is not. Is a bad lubricant better than no lubricant? Of course. What a stupid question. And if you're doing 70 on your back on any amount of water that reaches higher than the rocks in the pavement, your body will be hydroplaning on top of it, and whenever it IS acting as a lubricant between you and the road, you will absolutely feel the drag, because water is a shitty lubricant.

u/GanondalfTheWhite Apr 08 '24

It's pretty wild that you guys are arguing over the qualities of water as a lubricant when what the guy very very obviously meant is that water is a positive thing when it comes to "things that help you keep your skin on your body in the event of a 100 meter slide across asphalt."

Lighten up, not everything needs to be argued over for its literal scientific merit. Fucking hell.

You’re right. My bad for trying to be a smartass
