During the Flow Measurement course taught in BTC's Instrumentation program, I have students build airspeed measurement systems using a pitot tube, a differential pressure transmitter, and a data acquisition device to measure the airspeed from a moving vehicle. Students gather "characteristic" data on the Pitot tube at a variety of airspeeds, then program the transmitter and data acquisition system to display characterized pressure measurements as airspeed in miles per hour. The math is identical to what would be done measuring the flow of any fluid through a pipe inferred from pressure measurements.

  • @no0bK1ll3r Why do you think in airplanes you get ground only ground speed? Because the plane has only GPS?

  • LOL in car it measures air speed but in airplanes you get ground speed (and afcourse you need the air speed)

  • Cool!
