Drag

Postby Corvus » Mon May 11, 2015 8:46 am

Read an article recently, about aero drag and motorbikes. Saying how unaerodynamic a motorbike was compared to a car. That a good indicator of the drag is how much power is consumed to propel the vehicle to a certain speed, given that aero drag is by far the most deciding factor at high speed.

I go along the power consumption thing, but I have difficulty with what represents drag.

Reason I say this is because it seems that a modern car will need double the horsepower to achieve the same speed as a bike. Looking around the 130 mph mark.

So if consumed horsepower is the indicator of drag, a bike Seems to have less of it.

Clearly there's more to overall drag than just a slippery shape.

Ok, when it comes to saving the planet, or at least the oil reserves, how efficiently the respective vehicle musters up its necessary horsepower is a different thing again.

Hey, what Tanneman gets up to in his spare time is no concern of mine.

Hijack away. If no one's interested then no one's interested. Again, no concern of mine.

:D
