Why Is Velocity Zero At Pitot Tube? Any point in a flow where V = 0 is called a stagnation point of the flow; hence, point B at the open face of the Pitot tube is a stagnation point, where VB = 0. In turn, from Bernoulli’s equation we know the pressure increases as the
How Does Pitot Tube Help In Measuring The Airspeed? Basically, a pitot tube is used in wind tunnel experiments and on airplanes to measure flow speed. It’s a slender tube that has two holes on it. … By measuring the difference between these pressures, you get the dynamic pressure, which can be used to calculate
What Does Flow Speed Depend On? What does flow speed depend on? In other words, speed increases when cross-sectional area decreases, and speed decreases when cross-sectional area increases. What does the flow rate depend on? Since liquids are incompressible fluids, their flow rate depends only on the difference between the inlet and outlet pressures (Δp,
