Please help: We know that static pressure is the pressure felt when moving with the fluid (air). So in real flight the Pitot-static tube is moving with the aircraft and gives static pressure X (lets call it X). BUT in a wind tunnel the Pitot static tube is fixed (i.e. not moving) and the static pressure is Y(lets call it Y). My question is X=Y? (assuming that air density, temperature etc. are all the same). I don't know if there is a simple answer to this, if there is then please explain!! Thanks in advance.
