High airflow velocity can never create low pressure!

Thats only a mathematical manipulation!


Tell that to all the tornado victims who have seen the
structure they were in explode from greater pressure
inside than outside because of winds up to 200mph
or greater creating sever low pressure.

You are clueless, man. Get outside once in a while
and observe things. Sitting at your desk and reading
what professorial types have written is not serving
you well at all.
