Above papers assume that there is an air velocity sensor such as a pitot tube for obtaining wind velocity measurement. A Pitot tube is fixed inside a pipe connected to a supply. using conventional auto-pilot sensors with exponentially correlated measurement errors. The static pressure can also be measured by inserting the other end of inverted U-tube to the pipes. Such an arrangement is known as вЂвЂ™Pitot-meter. This equation can be rearranged and used to solve for fluid velocity or difference in height of the fluids in the manometer: If, now, the tubes are connected by an inverted U-tube manometer, the difference of water height вЂhвЂ™ will give the velocity head. The equation for the difference in pressure in a manometer is substituted into the simplified Bernoulli equation: Thus we obtain the simplified form of Bernoulli's equation: The point velocities can be used to calculate the average velocity that can be used to estimate the flow. The two points that are being evaluated are at the same height, so and drop out. All terms on the right side refer to point 2, a point upstream from the pitot tube. Bernoulli's equation is used to calculate the velocity of the bulk fluid in the pipe by using this pressure difference in the pitot tube:ДЄll terms on the left side represent the stagnation point (entrance of the pitot tube) here is the stagnation pressure and is the velocity of fluid in the pipe at point 1.

The Pitot tube is connected to a pressure transducer along with a digital.

Some kinetic energy density of the fluid flowing through the pipe is converted into pressure, resulting in a change in manometer height. monitor and control the temperature and free stream velocity, respectively. Pitot tubes are based on BernoulliвЂ™s equation, which states an increase in the speed of a fluid occurs simultaneously with an increase in dynamic pressure and a decrease in static pressure. Pitot tubes are used to measure the velocity of a fluid moving through a pipe by taking advantage of the fact that the velocity at the height of the bend in the tube (stagnation point) is zero. Dwyer Instruments offers many styles of Pitot tubes, which are a commonly used sensor for monitoring air velocity and flow rate in heating, ventilation, and air conditioning.
