1.	How does the pitot tube help in measuring the airspeed?(a) Using temperature(b) Using velocity(c) Using mach number(d) Using the pressure differenceThe question was asked in an international level competition.Origin of the question is Pitot Tube topic in division Inviscid & Incompressible Flow of Aerodynamics
Answer» The correct OPTION is (d) USING the pressure difference The best I can EXPLAIN: The pitot tube is closed at one end and is opened from other ends. When the air is filled inside the tube, the pressure at the open end equals to total pressure and it DIFFERS from the pressure outside the tube. Using this pressure difference and applying Bernoulli’s equation, the speed of air can be calculated.
