Tell that to cyclists :-) You can barely go above 25 km/h (~15 mph) without feeling like you are just pedaling to overcome the drag.
Reducing the Cd on a bike, ie going recumbent and putting a aerodynamic shell on it, ie switching to a velomobile allows you to go 40 km/h (~25 mph) with relative ease.
- Toutouxc 5y agoJust in case you misunderstood the parent post -- your Cd as a cyclist is pretty much constant around your normal cycling speeds. Your total air drag goes up with the square of velocity, that's for sure, but if you went transsonic on your bike, your Cd would ALSO increase dramatically on top of the already brutal velocity-squared multiplier.
- rich_sasha 5y agoIt’s almost worse, because you’re working against this quadratic force, at a rate proportional to speed. So power output, the usual limiting factor for a cyclist, scales like 3rd power of speed.
- fho 5y agoFair enough ... I really did not get that :-)
