What causes water to come out the tail pipe?

[Chunkee]

At lunch today, I followed a car that had water pouring out its tailpipe....i see it alot.

Isn't H2O a product of combustion? How much water are we talking about...

a) drip drip drip
b) pouring
c) GUSH

Head gasketage.

err...maybe not if you see it alot..and it was just water.

 

[Bassyhead]

water is produced as a result of combustion

I would guess condensation on the inside of the exhaust pipe.

Yup, once the car is fully warmed up & the exhaust is hot you won't see it anymore.

Not entirely true. It's still there, its just as a vapor.

Whenever you burn a hydrocarbon (and several other materials) you will get water. This is first year chem, folks. Everyone here that has been through (or started) highschool should know this.

if it try to remember that far back about something i disliked so much, my pancreas start to hurt

Maybe your town is filled with hydrogen fuel-cell powered vehicles? Then again, maybe not.

Condensation.

You have won nerd of the year who posted something technical in the off topic forum award.

I didn't say it wouldn't be there, I said you wouldn't see it anymore.

With the copious amount of hard liquor I consumed in college, I am lucky that I even remember going to highschool.

Water is a by-product on the catalytic converters when the change the carbon monoxide and nitrates of oxide to carbon dioxide and water and combustion as noted above.

You have won dork of the year for thinking that a high school level chemistry equation is technical.

You mean idiot of the year?

I was going to post the formula when I first read this thread, but forgot how many carbon atoms were in gasoline. Then after seeing your post, I was like, "Durh, octane..."

<----- needs to go back to school

No, but you agreed that it was condensation, which it ain't

here be the double post

post + too many nefs ------> double post + fsck

Where be the carbon monoxide? (CO)

 

[element]

The right equation is this one:

burning octane:

C8H18 + O2 ==> aCO2 + bCO + cH2O + unburnt hydrocarbons
Where a, b, & c depend on the amaount of available oxygen.

The one posted earlier only occurs during complete combustion. This is the formula for incomplete combustion (car engine)
