Rear Windshield Wiper

[jut703]

Mga sir curious lang, bakit yung mga car na mas steep yung rear windshield lang yung may rear windshield wiper? Bat yung mga sedan wala?

Forgive me if I screw up my physics, pero diba mas likely na magslide downward yung tubig kapag mas steep kasi diba Force of gravity x sin theta where theta is yung angle of inclination, so mas malakas gravity kapag steep?

Salamat. :D

if you are referring to vans and hatch-backs, they create more turbulence on their rears which causes the air together with the muddied rain water to hit the rear windshield making visibility almost zero in just a few hundred meters.

hmmm...pwede kayang lagyan ng maliit na spoiler yung van pero pababa yung porma nya para mabawasan yun vacuum effect..? or any ideas para mabawasan yung vacuum effect niya..?

Its not gravity, it's air turbulence. Dirt and water tends to collect on such vehicles because of poor aerodynamics at the rear window. So the simple solution to keep good visibility is to add a rear wiper.

Adding a roof spoiler won't do enough or makes it worst.

jut703,
if you have rear windshield, try driving in reverse. most of the cars i know have windshields and rear window

Oooops, there is some breakdown in communication here. I believe the thread starter is referring to the rear glass or window, whatever you call it of some vehicles that are also equipped with wiper blades, aside from the front windshield, which is always equipped with wiper blades on standard vehicles.

Oh, I see. Thanks guys. I never would've thought of turbulence )

Ay. Namilosopo.

Yeah I meant the rear window. :D I had the subconscious notion of calling it a rear windshield since its about as big as the windshield up front so it seemed more of a windshield than a window to me (as I've never owned a hatchback). :D
