yeah i had two bikes i knew that i was "cooltrolling" take this other cool trol
a pitot tube has in one end v=0 and in other v= wind speed
from this theres a pressure gradient which creates a column of fluid
from the height of this fluid apllying bernuiili you know the speed
you know where the caught is and you should never tell in an exam
velocity=0 both if the tube is facing the wind or oposite to the wind
in other words presure in the mouth is identical if your going forward than if your going backwards
of course this is a lie but if this is difficult for you to digest you can call it a simplification with a more complex reality in whcih other factors play role
