Pitot pressure

Well Known Member
Can anyone tell me what range of pressures there are in a pitot tube in PSI or mbars?
And point me to a good source of this info?

Thanks,

Tom
 
If you are wanting to calibrate an airspeed indicator with a water manometer, then you will need at least 24" of gauge height.
At 180 KIAS the pitot pressure is equivalent to 21" of water (about 0.8 psi).

There are several online calculators such as this.
