Measuring Flow Rates with a Pitot Tube

Sep 26, 2014A pitot tube determines the velocity of a fluid by measuring the fluid's stagnation pressure. In this demonstration, stagnation pressure is measured with a manometer. The height differential in the manometer is a function of the manometer fluid density, and the flowing fluid's kinetic energy. Bernoulli's equation relates these terms, and is
