Well, it's clear astjp2 won the thread with an actual graph of pressure vs. airspeed.
Be careful with that conclusion, there have been graphs shown by parties here with opposing views, interpreting the graphs is the key. I'll try to find the graph of protagonist "certainty" vs intelligence.
PS read my sig link.
So you are saying that every aircraft that uses an airspeed indicator is wrong? Or that my graphic is bad data? That is where those numbers come from. The size of the opening does not change the pressure either, a 1/4" pitot and a 3" have the same pressure, the larger one has more overall force because of the cross section but the pressure inside is the same.
