pitot tube to measure speed and bernuoilli, aeronautics

[raaaid]

i see thanks

so if both tubes are paralel to the wind but opposite sense it wont work, it will be a column of 0 since as you explain both measure dinamic pressure

but doesnt this contradict common sense?

my imagination tells me there will be a column so high the fluid will even be exppeled form the bachk tube

id say though though both measure dynamic pressure those presures have opposite sense

could the petrol companies promote fake science in schools? could they rewrite science as they rewrite history?

edit:

imagine your in an exam and you are given this problem:


a special pitot tube with both ends parallel to the flow of wind but oposite sense is in an ideal fluid at an speed of 1 m/s

what will be the height of the mercury?

i have no clue how to solve this problem since i would apply bernuilli formula considering v=0 in both ends which would give me a result of a column of height zero which is obviously false
