yes but im more interested not in the practice but how to solve the problem applying bernuoilli

on a normal pitot tube you account for the amount of wind speed in the perpendicular to the wind tube and zero speed in the paralel to the wind tube

voila you get the height applying bernuoilli formula

but how could you apply bernuoilli if both tubes are parallel but opposite?

in both speed is zero so according bernuilli the column should have zero height

is then bernuilli wrong and should be completed with things like coanda?

maybe this is not the place to ask but im sure somebody knows and its aeronautics after all

im permabanned from the main physics forums for not accepting mainstream, i got my physics tutor confused with this question and i dont want to ask my teacher cause he would probably not know and leave me in a bad place
