1. Explain the operation of a Pitot Tube velocity meter – how is it used to measure wind speed or air velocity? Include a sketch of the device clearly indicating pressure tappings for connection to a manometer or differential pressure sensor.
2. Derive the equation that relates velocity to pressure drop for the Pitot Tube. Start with Bernoulli’s equation.
3. Sketch the relationship between velocity and pressure drop across the static and stagnation tappings on a Pitot Tube. Show velocity on the x-axis as that is the variable that is changed to create a change in pressure drop which is measured.
4. A Pitot Tube is installed on a water pipe to measure the velocity and flowrate of the water. The pipe is 200 mm in diameter. A pressure drop of 6 mbar is measured by a manometer connected to the Pitot Tube. Given the equation for the Pitot Tube, calculate the velocity, volumetric flowrate and mass flowrate of the water.
5. Explain the
principle of operation of a cup anemometer that is connected to a simple
