Oh fucrk your impellor all over again

He quoted the same chit from wikipedia a wile back

U will be tarnished with the wankr brush from here on in bud

Congrats !!

OK this table should answer most questions about colour. To sum up. If its black or white it does not make a dramatic difference. Most coloured mat surfaces will emisify a fair bit of heat. The big take out is that polished metal surfaces (aluminium, cooper, stailness etc. Do not emisify much heat at all. In other words the dont absorb heat very well and they do not give off heat very well (when compared to a matt surface of any colour).

Emissivity Table

Emissivity is a measure of the efficiency in which a surface emits thermal energy. It is defined as the fraction of energy being emitted relative to that emitted by a thermally black surface (a black body). A black body is a material that is a perfect emitter of heat energy and has an emissivity value of 1. A material with an emissivity value of 0 would be considered a perfect thermal mirror.

For example, if an object had the potential to emit 100 units of energy but only emits 90 units in the real world, then that object would have an emissivity value of 0.90. In the real world there are no perfect "black bodies" and very few perfect infrared mirrors so most objects have an emissivity between 0 and 1.

The accuracy of the following figures is almost impossible to guarantee as the emissivity of a surface will not only alter with regard to texture and colour but also with its actual temperature at the time of measurement. We would recommend, in the first instance, comparing measurements found, with an accurate surface probe or wire probe, and then the Infrared thermometer can be adjusted to match the correct emissivity and used for subsequent measurements.

No responsibility can be assumed by ThermoWorks for the accuracy or otherwise of the following figures.

Sorry that my posts offend you so greatly. Just trying to learn and share. You have my permission to not read them if you wish.

[JETURBO]

and u will have the joy of being reffered to as arse clown number 2 of the forum

cheers

I'm shooting for the number 1 posi.

For anybody who is reading this with the view of actually choosing what surfaces to use on their vehicles please consider that. Emissivity is only one way to move heat. We also have conduction and convection. Convection being the one we car folk probably know the most about ie. the heat transfer through contact with air or water. Just didnt want people to think that a polished surface will transmit stuff all heat. It will still transmit heaps just not as much as say the same object in matt black.

With regards to painting the intercooler matt black. Looks like it will have a benificial effect (provided its not a special insulating paint) but we would probably need to dip the intercooler in a tank of the stuff to reach all the fins.

ok point taken... going to go paint everything on my car red now...

coz red's faster right?

Right, I'm even writting faster now.

dude, you may be technically right, but 3/8ths of stuff all of members on here give a sh*t about it.

j@t is right. impellor already has wanker tattoo'd all over him on here, and I reckon you'll be next.

dont get me wrong, j@t's a wanker too, but theres wankers , and theres wankers....

^^speaking of wankers...
